Potential functions and mechanisms of lysine crotonylation modification (Kcr) in tumorigenesis and lymphatic metastasis of papillary thyroid cancer (PTC). J Transl Med 2024; 22:874. [PMID: 39342359 PMCID: PMC11439252 DOI: 10.1186/s12967-024-05651-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2024] [Accepted: 09/16/2024] [Indexed: 10/01/2024] Open
Abstract
OBJECTIVES To examine the putative functions and mechanisms of lysine crotonylation (Kcr) during the development and progression of papillary thyroid cancer (PTC). METHODS Samples of thyroid cancer tissues were collected and subjected to liquid chromatography-tandem mass spectrometry. Crotonylated differentially expressed proteins (DEPs) and differentially expressed Kcr sites (DEKSs) were analyzed by Motif, dynamic expression model analysis (Mfuzz), subcellular localization, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway annotation, Go Ontology (GO) annotation, and protein-protein interaction analysis (PPI). Validation was performed by immunohistochemistry (IHC). RESULTS A total of 262 crotonylated DEPs and 702 DEKSs were quantitated. First, for the tumor/normal comparison, a dynamic expression model analysis (Mfuzz) of the DEKSs revealed that clusters 1, 3, and 4 increased with the progression of thyroid cancer; however, cluster 6 showed a dramatic increase during the transition from N0-tumor to N1-tumor. Furthermore, based on GO annotation, KEGG, and PPI, the crotonylated DEPs were primarily enriched in the PI3K-Akt signaling pathway, Cell cycle, and Hippo signaling pathway. Of note, crosstalk between the proteome and Kcr proteome suggested a differential changing trend, which was enriched in Thyroid hormone synthesis, Pyruvate metabolism, TCA cycle, Cell cycle, and Apoptosis pathways. Similarly, for the LNM comparison group, the DEKSs and related DEPs were primarily enriched in Hydrogen peroxide catabolic process and Tight junction pathway. Finally, according to The Cancer Genome Atlas Program (TCGA) database, the differential expression of Kcr DEPs were associated with the prognosis of thyroid cancer, indicating the prognostic significance of these proteins. Moreover, based on the clinical validation of 47 additional samples, Kcr was highly expressed in thyroid tumor tissues compared with normal tissue (t = 9.792, P < 0.001). In addition, a positive correlation was observed between Kcr and N-cadherin (r = 0.5710, P = 0.0015). Moreover, N-cadherin expression was higher in the relatively high Kcr expression group (χ2 = 18.966, P < 0.001). CONCLUSIONS Higher Kcr expression was correlated with thyroid tumorigenesis and lymphatic metastasis, which may regulate thyroid cancer progression by Pyruvate metabolism, TCA cycle, Cell cycle, and other pathways.

Abstract
Protein lysine crotonylation (Kcr) is one conserved form of posttranslational modifications of proteins, which plays an important role in a series of cellular physiological and pathological processes. Lysine ε-amino groups are the primary sites of such modification, resulting in four-carbon planar lysine crotonylation that is structurally and functionally distinct from the acetylation of these residues. High levels of Kcr modifications have been identified on both histone and non-histone proteins. The present review offers an update on the research progression regarding protein Kcr modifications in biomedical contexts and provides a discussion of the mechanisms whereby Kcr modification governs a range of biological processes. In addition, given the importance of protein Kcr modification in disease onset and progression, the potential viability of Kcr regulators as therapeutic targets is elucidated.

[PMID: 38750524 PMCID: PMC11094900 DOI: 10.1186/s12915-024-01917-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2023] [Accepted: 05/10/2024] [Indexed: 05/19/2024] Open
Abstract
BACKGROUND Protein posttranslational modifications (PTMs) are fast and early responses to environmental changes, including pathogen infection. Jujube witches' broom (JWB) is a phytoplasma disease causing great economic loss in jujube production. After phytoplasma infection, the transcriptional, translational, and metabolic levels in jujube were activated, enabling it to survive during phytoplasma invasion. However, no study has yet reported on PTMs in jujube. Lysine crotonylation (Kcr) and lysine succinylation (Ksu) have been popular studies in recent years and their function in plant phytoplasma-stress responses remains unclear. RESULTS Here, 1656 crotonylated and 282 succinylated jujube proteins were first identified under phytoplasma-stress, of which 198 were simultaneously crotonylated and succinylated. Comparative analysis revealed that 656 proteins, 137 crotonylated and 43 succinylated proteins in jujube were regulated by phytoplasma infection, suggesting that Kcr was more universal than Ksu. Kcr differentially expressed proteins (DEPs) were related to ribosomes, photosynthetic and carbon metabolism, while Ksu DEPs were mainly involved in carbon metabolism, the TCA cycle and secondary metabolite biosynthesis. The crosstalk network among proteome, crotonylome and succinylome showed that DEPs related to ribosomal, peroxidases and glutathione redox were enriched. Among them, ZjPOD51 and ZjPHGPX2 significantly increased at the protein and Kcr level under phytoplasma-stress. Notably, 7 Kcr sites were identified in ZjPHGPX2, a unique antioxidant enzyme. After inhibitor nicotinamide (NAM) treatment, GPX enzyme activity in jujube seedlings was reduced. Further, site-directed mutagenesis of key Kcr modification sites K130 and/or K135 in ZjPHGPX2 significantly reduced its activity. CONCLUSIONS This study firstly provided large-scale datasets of Kcr and Ksu in phytoplasma-infected jujube and revealed that Kcr modification in ZjPHGPX2 positively regulates its activity.

LMCrot: an enhanced protein crotonylation site predictor by leveraging an interpretable window-level embedding from a transformer-based protein language model. Bioinformatics 2024; 40:btae290. [PMID: 38662579 PMCID: PMC11088740 DOI: 10.1093/bioinformatics/btae290] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2023] [Revised: 02/13/2024] [Accepted: 04/24/2024] [Indexed: 05/13/2024] Open
Abstract
MOTIVATION Recent advancements in natural language processing have highlighted the effectiveness of global contextualized representations from protein language models (pLMs) in numerous downstream tasks. Nonetheless, strategies to encode the site-of-interest leveraging pLMs for per-residue prediction tasks, such as crotonylation (Kcr) prediction, remain largely uncharted. RESULTS Herein, we adopt a range of approaches for utilizing pLMs by experimenting with different input sequence types (full-length protein sequence versus window sequence), assessing the implications of utilizing per-residue embedding of the site-of-interest as well as embeddings of window residues centered around it. Building upon these insights, we developed a novel residual ConvBiLSTM network designed to process window-level embeddings of the site-of-interest generated by the ProtT5-XL-UniRef50 pLM using full-length sequences as input. This model, termed T5ResConvBiLSTM, surpasses existing state-of-the-art Kcr predictors in performance across three diverse datasets. To validate our approach of utilizing full sequence-based window-level embeddings, we also delved into the interpretability of ProtT5-derived embedding tensors in two ways: firstly, by scrutinizing the attention weights obtained from the transformer's encoder block; and secondly, by computing SHAP values for these tensors, providing a model-agnostic interpretation of the prediction results. Additionally, we enhance the latent representation of ProtT5 by incorporating two additional local representations, one derived from amino acid properties and the other from supervised embedding layer, through an intermediate fusion stacked generalization approach, using an n-mer window sequence (or, peptide/fragment). The resultant stacked model, dubbed LMCrot, exhibits a more pronounced improvement in predictive performance across the tested datasets. AVAILABILITY AND IMPLEMENTATION LMCrot is publicly available at https://github.com/KCLabMTU/LMCrot.

Abstract
BACKGROUND Lysine crotonylation (Kcr) is a crucial protein post-translational modification found in histone and non-histone proteins. It plays a pivotal role in regulating diverse biological processes in both animals and plants, including gene transcription and replication, cell metabolism and differentiation, as well as photosynthesis. Despite the significance of Kcr, detection of Kcr sites through biological experiments is often time-consuming, expensive, and only a fraction of crotonylated peptides can be identified. This reality highlights the need for efficient and rapid prediction of Kcr sites through computational methods. Currently, several machine learning models exist for predicting Kcr sites in humans, yet models tailored for plants are rare. Furthermore, no downloadable Kcr site predictors or datasets have been developed specifically for plants. To address this gap, it is imperative to integrate existing Kcr sites detected in plant experiments and establish a dedicated computational model for plants. RESULTS Most plant Kcr sites are located on non-histones. In this study, we collected non-histone Kcr sites from five plants, including wheat, tabacum, rice, peanut, and papaya. We then conducted a comprehensive analysis of the amino acid distribution surrounding these sites. To develop a predictive model for plant non-histone Kcr sites, we combined a convolutional neural network (CNN), a bidirectional long short-term memory network (BiLSTM), and attention mechanism to build a deep learning model called PlantNh-Kcr. On both five-fold cross-validation and independent tests, PlantNh-Kcr outperformed multiple conventional machine learning models and other deep learning models. Furthermore, we conducted an analysis of species-specific effect on the PlantNh-Kcr model and found that a general model trained using data from multiple species outperforms species-specific models. CONCLUSION PlantNh-Kcr represents a valuable tool for predicting plant non-histone Kcr sites. We expect that this model will aid in addressing key challenges and tasks in the study of plant crotonylation sites.

Abstract
Lysine crotonylation (Kcr) is a newly discovered type of post-translational modification. Although Kcr has been reported in several species, its role in crustaceans remains largely unknown. In this study, Kcr in hemocytes of mud crab (Scylla paramamosain) was characterized using pan anti-crotonyllysine antibody enrichment and high-resolution liquid chromatogram-mass spectrometry analysis after SpTRAF6 or SpEcsit silencing. Altogether, 1,800 Kcr sites with six conserved motifs were identified from 512 proteins. Subcellular localization analysis showed that the identified Kcr proteins were mainly localized to the cytoplasm, nucleus, and mitochondria. The cellular components analysis showed that the 'chromosomal region' was enriched in the hemocytes of SpTRAF6-or SpEcsit-silenced mud crabs. The KEGG and PPI analyses showed that the identified Kcr proteins in the hemocytes SpTRAF6-or SpEcsit-silenced mud crabs were related to the 'protein processing in endoplasmic reticulum'; of which the marker of endoplasmic reticulum stress (Bip) was identified to be crotonylated. These datasets present the first comprehensive analysis of the crotonylome in mud crab hemocytes, providing invaluable insights into the regulatory functions of SpTRAF6 and SpEcsit in Kcr. Additionally, our findings shed light on the potential role of these proteins in activating marker proteins during endoplasmic reticulum stress in invertebrates.

Abstract
DNA damage caused by internal or external factors lead to increased genomic instability and various diseases. The DNA damage response (DDR) is a crucial mechanism that maintaining genomic stability through detecting and repairing DNA damage timely. Post-translational modifications (PTMs) play significant roles in regulation of DDR. Among the present PTMs, crotonylation has emerged as a novel identified modification that is involved in a wide range of biological processes including gene expression, spermatogenesis, cell cycle, and the development of diverse diseases. In the past decade, numerous crotonylation sites have been identified in histone and non-histone proteins, leading to a more comprehensive and deep understanding of the function and mechanisms in protein crotonylation. This review provides a comprehensive overview of the regulatory mechanisms of protein crotonylation and the effect of crotonylation in DDR. Furthermore, the effect of protein crotonylation in tumor development and progression is presented, to inspire and explore the novel strategies for tumor therapy.

Abstract
BACKGROUND Blood-based tests have public appeal in screening cancers due to their minimally invasive nature, ability to integrate with other routine blood tests, and high compliance. This study aimed to investigate whether certain epigenetic modulation of peripheral blood mononuclear cells (PBMCs) could be a biomarker of colorectal cancer (CRC). RESULTS Western blotting of histones in the PBMCs from 40 colorectal cancer patients and 40 healthy controls was performed to identify the crotonylation sites of proteins. The correlation of crotonylation with tumor staging and diagnostic efficacy were analyzed. Crotonylation of H2BK12 (H2BK12cr) was identified significantly upregulated in the PBMCs of CRC patients compared to healthy controls, and were closely related to distant metastasis (P = 0.0478) and late TNM stage (P = 0.0201). Receiver operator characteristic curve (ROC) analysis demonstrated that the area under curve (AUC) of H2BK12cr was 0.8488, the sensitivity was 70%, and the specificity was 92.5%. The H2BK12cr parameter significantly increased the diagnostic effectiveness of CRC compared with the commercial carcinoembryonic antigen assays. CONCLUSIONS The H2BK12cr level in PBMCs of CRC patients has a potential to be a biomarker for distinguishing CRC patients from healthy controls with the advantages of easy operation and high diagnostic efficacy.

Abstract
Here, we reported the complete profiling of the crotonylation proteome in common wheat. Through a combination of crotonylation and multi-omics analysis, we identified a TaPGK associated with wheat cold stress. Then, we confirmed the positive role of TaPGK-modulating wheat cold tolerance. Meanwhile, we found that cold stress induced lysine crotonylation of TaPGK. Moreover, we screened a lysine decrotonylase TaSRT1 interacting with TaPGK and found that TaSRT1 negatively regulated wheat cold tolerance. We subsequently demonstrated TaSRT1 inhibiting the accumulation of TaPGK protein, and this inhibition was possibly resulted from decrotonylation of TaPGK by TaSRT1. Transcriptome sequencing indicated that overexpression of TaPGK activated glycolytic key genes and thereby increased pyruvate content. Moreover, we found that exogenous application of pyruvate sharply enhanced wheat cold tolerance. These findings suggest that the TaSRT1-TaPGK model regulating wheat cold tolerance is possibly through mediating pyruvate. This study provided two valuable cold tolerance genes and dissected diverse mechanism of glycolytic pathway involving in wheat cold stress.

Cross-Platform Comparison of Amino Acid Metabolic Profiling in Three Model Organisms Used in Environmental Metabolomics. Metabolites 2023; 13:metabo13030402. [PMID: 36984842 PMCID: PMC10058405 DOI: 10.3390/metabo13030402] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2023] [Revised: 02/28/2023] [Accepted: 03/01/2023] [Indexed: 03/11/2023] Open
Abstract
Environmental metabolomics is a promising approach to study pollutant impacts to target organisms in both terrestrial and aquatic environments. To this end, both nuclear magnetic resonance (NMR)- and mass spectrometry (MS)-based methods are used to profile amino acids in different environmental metabolomic studies. However, these two methods have not been compared directly which is an important consideration for broader comparisons in the environmental metabolomics field. We compared the quantification of 18 amino acids in the tissue extracts of Daphnia magna, a common model organism used in both ecotoxicology and ecology, using both 1H NMR spectroscopy and liquid chromatography with tandem MS (LC-MS/MS). 1H NMR quantification of amino acids agreed with the LC-MS/MS quantification for 17 of 18 amino acids measured. We also tested both quantitative methods in a D. magna sub-lethal exposure study to copper and lithium. Again, both NMR and LC-MS/MS measurements showed agreement. We extended our analyses with extracts from the earthworm Eisenia fetida and the plant model Nicotiana tabacum. The concentrations of amino acids by both 1H NMR and LC-MS/MS, agreed and demonstrated the robustness of both techniques for quantitative metabolomics. These findings demonstrate the compatibility of these two analytical platforms for amino acid profiling in environmentally relevant model organisms and emphasizes that data from either method is robust for comparisons across studies to further build the knowledge base related to pollutant exposure impacts and toxic responses of diverse environmental organisms.

Abstract
Lysine crotonylation as a protein post-translational modification regulates diverse cellular processes and functions. However, the role of crotonylation in nutrient signaling pathways remains unclear. Here, we find a positive correlation between global crotonylation levels and leucine-deprivation-induced autophagy. Crotonylome profiling identifies many crotonylated proteins regulated by leucine deprivation. Bioinformatics analysis dominates 14-3-3 proteins in leucine-mediated crotonylome. Expression of 14-3-3ε crotonylation-deficient mutant significantly inhibits leucine-deprivation-induced autophagy. Molecular dynamics analysis shows that crotonylation increases molecular instability and disrupts the 14-3-3ε amphipathic pocket through which 14-3-3ε interacts with binding partners. Leucine-deprivation-induced 14-3-3ε crotonylation leads to the release of protein phosphatase 1B (PPM1B) from 14-3-3ε interaction. Active PPM1B dephosphorylates ULK1 and subsequently initiates autophagy. We further find that 14-3-3ε crotonylation is regulated by HDAC7. Taken together, our findings demonstrate that the 14-3-3ε-PPM1B axis regulated by crotonylation may play a vital role in leucine-deprivation-induced autophagy.

PLANTS (BASEL, SWITZERLAND) 2022; 11:2807. [PMID: 36365261 PMCID: PMC9657071 DOI: 10.3390/plants11212807] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 08/03/2022] [Revised: 10/17/2022] [Accepted: 10/17/2022] [Indexed: 06/16/2023]
Abstract
While wheat (Triticum aestivum L.) is a widely grown and enjoyed crop, the diverse and complex global situation and climate are exacerbating the instability of its supply. In particular, pre-harvest sprouting (PHS) is one of the major abiotic stresses that frequently occurs due to irregular climate conditions, causing serious damage to wheat and its quality. In this study, transcriptomic analysis with RNA-seq and proteomic analysis with LC-MS/MS were performed in PHS-treated spikes from two wheat cultivars presenting PHS sensitivity and tolerance, respectively. A total of 13,154 differentially expressed genes (DEGs) and 706 differentially expressed proteins (DEPs) were identified in four comparison groups between the susceptible/tolerant cultivars. Gene function and correlation analysis were performed to determine the co-profiled genes and proteins affected by PHS treatment. In the functional annotation of each comparative group, similar functions were confirmed in each cultivar under PHS treatment; however, in Keumgang PHS+7 (K7) vs. Woori PHS+7 (W7), functional annotations presented clear differences in the "spliceosome" and "proteasome" pathways. In addition, our results indicate that alternative splicing and ubiquitin-proteasome support the regulation of germination and seed dormancy. This study provides an advanced understanding of the functions involved in transcription and translation related to PHS mechanisms, thus enabling specific proposals for the further analysis of germination and seed dormancy mechanisms and pathways in wheat.

Abstract
BACKGROUND Pinellia ternata is an important traditional medicine in China, and its growth is regulated by the transcriptome or proteome. Lysine crotonylation, a newly identified and important type of posttranslational modification, plays a key role in many aspects of cell metabolism. However, little is known about its functions in Pinellia ternata. RESULTS In this study, we generated a global crotonylome analysis of Pinellia ternata and examined its overlap with lysine succinylation. A total of 2106 crotonylated sites matched on 1006 proteins overlapping in three independent tests were identified, and we found three specific amino acids surrounding crotonylation sites in Pinellia ternata: KcrF, K***Y**Kcr and Kcr****R. Gene Ontology (GO) and KEGG pathway enrichment analyses showed that two crucial alkaloid biosynthesis-related enzymes and many stress-related proteins were also highly crotonylated. Furthermore, several enzymes participating in carbohydrate metabolism pathways were found to exhibit both lysine crotonylation and succinylation modifications. CONCLUSIONS These results indicate that lysine crotonylation performs important functions in many biological processes in Pinellia ternata, especially in the biosynthesis of alkaloids, and some metabolic pathways are simultaneously regulated by lysine crotonylation and succinylation.

Malonylome analysis uncovers the association of lysine malonylation with metabolism and acidic stress in pathogenic Mycobacterium tuberculosis. Microbiol Res 2022; 265:127209.

Abstract
Mycobacterium tuberculosis (Mtb), the pathogenic agent of tuberculosis, remains a primary inducement of morbidity and mortality globally. Mtb have evolved mechanisms to recognize diverse signals, such as acidic pH within phagolysosomes and therefore to reprogram multiple physiological and metabolic processes to adapt to intracellular survival. Moreover, lysine malonylation has been suggested to participate in regulation of enzymes in carbon metabolism. However, lysine malonylation in Mtb and its association with acidic pH associated metabolism adaptation remain unknown. Here, we systematically characterized the comparative malonylome of Mtb H37Rv grown in normal (7H9-Tyloxapol (Ty)-7.4) and acidic (7H9-Ty-4.5) medium mimicking lysosome pH. In total, 2467 lysine malonylation sites within 1026 proteins were identified, which related to diverse biological processes, particularly accumulated in metabolic process. 1090 lysine malonylation sites from 562 proteins were quantified, among which 391 lysine malonylation sites in 273 protein were down-regulated while 40 lysine malonylation sites from 36 proteins were up-regulated in acidic medium, indicating that malonylation may participate in acidic pH associated metabolism. Accordingly, the enzyme activity of GlcB was reduced under acidic stress corresponding to decreased malonylation of GlcB compared with that of normal condition and this was further demonstrated by site-specific mutations. We further found that Mtb-CobB, a sirtuin-like deacetylase and desuccinylase, involved in demalonylase activity. Together, the Mtb malonylome not only indicates the critical role of malonylation in metabolism regulation, but may provide new insights of malonylation on metabolism adaptation to acidic micro-environment in vivo.

Abstract
The high-altitude environment is characterized by hypobaric hypoxia, low temperatures, low humidity, and high radiation, which is a natural challenge for lowland residents entering. Previous studies have confirmed the acute and chronic effects of high altitude on the cardiovascular systems of lowlanders. Abnormal cardiovascular complications, including pulmonary edema, cardiac hypertrophy and pulmonary arterial hypertension were commonly explored. Effective evaluation of cardiovascular adaptive response in high altitude can provide a basis for early warning, prevention, diagnosis, and treatment of altitude diseases. At present, post-translational modifications (PTMs) of proteins are a key step to regulate their biological functions and dynamic interactions with other molecules. This process is regulated by countless enzymes called “writer, reader, and eraser,” and the performance is precisely controlled. Mutations and abnormal expression of these enzymes or their substrates have been implicated in the pathogenesis of cardiovascular diseases associated with high altitude. Although PTMs play an important regulatory role in key processes such as oxidative stress, apoptosis, proliferation, and hypoxia response, little attention has been paid to abnormal cardiovascular response at high altitude. Here, we reviewed the roles of PTMs in driving abnormal cardiovascular complications at high altitude.

[PMID: 36193016 DOI: 10.1111/ppl.13794] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/22/2022] [Revised: 09/08/2022] [Accepted: 09/29/2022] [Indexed: 06/16/2023]
Abstract
Protein acetylation and crotonylation are important posttranslational modifications of lysine. In animal cells, the correlation of acetylation and crotonylation has been well characterized and the lysines of some proteins are acetylated or crotonylated depending on the relative concentrations of acetyl-CoA and crotonyl-CoA. However, in plants, the correlation of acetylation and crotonylation and the effects of the relative intracellular concentrations of crotonyl-CoA and acetyl-CoA on protein crotonylation and acetylation are not well known. In our previous study, PaACL silencing changed the content of acetyl-CoA in petunia (Petunia hybrida) corollas, and the effect of PaACL silencing on the global acetylation proteome in petunia was analyzed. In the present study, we found that PaACL silencing did not significantly alter the content of crotonyl-CoA. We performed a global crotonylation proteome analysis of the corollas of PaACL-silenced and control petunia plants; we found that protein crotonylation was closely related to protein acetylation and that proteins with more crotonylation sites often had more acetylation sites. Crotonylated proteins and acetylated proteins were enriched in many common Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways. However, PaACL silencing resulted in different KEGG pathway enrichments of proteins with different levels of crotonylation sites and acetylation sites. PaACLB1-B2 silencing did not led to changes in the opposite direction in crotonylation and acetylation levels at the same lysine site in cytoplasmic proteins, which indicated that cytoplasmic lysine acetylation and crotonylation might not depend on the relative concentrations of acetyl-CoA and crotonyl-CoA. Moreover, the global crotonylome and acetylome were weakly positively correlated in the corollas of PaACL-silenced and control plants.

Lysine decrotonylation of glutathione peroxidase at lysine 220 site increases glutathione peroxidase activity to resist cold stress in chrysanthemum. ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2022; 232:113295. [PMID: 35151212 DOI: 10.1016/j.ecoenv.2022.113295] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/12/2021] [Revised: 02/03/2022] [Accepted: 02/06/2022] [Indexed: 06/14/2023]
Abstract
Lysine crotonylation is a protein post-translational modification that has been newly discovered in recent years. There are few studies on the lysine crotonylation of proteins in plants, and their functions in response to cold stress are still unclear. In this study, the chrysanthemum (Chrysanthemum morifolium Ramat.) glutathione peroxidase (GPX) gene was selected and named DgGPX1, and was found to be responsive to low temperature. Overexpression of DgGPX1 improved the cold resistance of transgenic chrysanthemum by increasing GPX activity to reduce the accumulation of reactive oxygen species (ROS) under low-temperature conditions. Furthermore, the level of DgGPX1 lysine crotonylation at lysine (K) 220 decreased under low temperature in chrysanthemum. Lysine decrotonylation of DgGPX1 at K220 further increased GPX activity to reduce ROS accumulation under cold stress, and thereby enhanced the cold resistance of chrysanthemum. The above results show that lysine decrotonylation of DgGPX1 at K220 increases GPX activity to resist cold stress in chrysanthemum.

Abstract
The lysine crotonylation of histone proteins is a newly identified posttranslational modification with diversified cellular functions. However, there are few reports on lysine crotonylation of non-histone proteins in medicinal plant cells. By using high-resolution liquid chromatography-mass spectrometry (LC-MS) coupled with highly sensitive-specific immune-affinity antibody analysis, a whole crotonylation proteome analysis of Dendrobium huoshanense was performed. In total, 1,591 proteins with 4,726 lysine crotonylation sites were identified; among them, 11 conserved motifs were identified. Bioinformatic analyses linked crotonylated proteins to the drought stress response and multiple metabolic pathways, including secondary metabolite biosynthesis, transport and catabolism, energy production and conversion, carbohydrate transport and metabolism, translation, and ribosomal structure and biogenesis. This study contributes toward understanding the regulatory mechanism of polysaccharide biosynthesis at the crotonylation level even under abiotic stress.

Abstract
Lysine crotonylation is a newly discovered and reversible posttranslational modification involved in various biological processes, especially metabolism regulation. A total of 5159 lysine crotonylation sites in 2272 protein groups were identified. Twenty-seven motifs were found to be the preferred amino acid sequences for crotonylation sites. Functional annotation analyses revealed that most crotonylated proteins play important roles in metabolic processes and photosynthesis. Bioinformatics analysis suggested that lysine crotonylation preferentially targets a variety of important biological processes, including ribosome, glyoxylate and dicarboxylate metabolism, carbon fixation in photosynthetic organisms, proteasome and the TCA cycle, indicating lysine crotonylation is involved in the common mechanism of metabolic regulation. A protein interaction network analysis revealed that diverse interactions are modulated by protein crotonylation. These results suggest that lysine crotonylation is involved in a variety of biological processes. HSP70 is a crucial protein involved in protecting plant cells and tissues from thermal or abiotic stress responses, and HSP70 protein was found to be crotonylated in paper mulberry. This systematic analysis provides the first comprehensive analysis of lysine crotonylation in paper mulberry and provides important resources for further study on the regulatory mechanism and function of the lysine crotonylated proteome.

Abstract
Fusarium oxysporum is one of the most important pathogenic fungi with a broad range of plant and animal hosts. The first key step of its infection cycle is conidial germination, but there is limited information available on the molecular events supporting this process. We show here that germination is accompanied by a sharp decrease in expression of FoSir5, an ortholog of the human lysine deacetylase SIRT5. We observe that FoSir5 decrotonylates a subunit of the fungal pyruvate dehydrogenase complex (FoDLAT) at K148, resulting in inhibition of the activity of the complex in mitochondria. Moreover, FoSir5 decrotonylates histone H3K18, leading to a downregulation of transcripts encoding enzymes of aerobic respiration pathways. Thus, the activity of FoSir5 coordinates regulation in different organelles to steer metabolic flux through respiration. As ATP content is positively related to fungal germination, we propose that FoSir5 negatively modulates conidial germination in F. oxysporum through its metabolic impact. These findings provide insights into the multifaceted roles of decrotonylation, catalyzed by FoSir5, that support conidial germination in F. oxysporum.

Abstract
Backgroud Streptococcus agalactiae is a common colonizer of the rectovaginal tract and lead to infectious diseases of neonatal and non-pregnant adults, which also causes infectious disease in fish and a zoonotic risk as well. Lysine crotonylation (Kcr) is a kind of histone post-translational modifications discovered in 2011. In yeast and mammals, Kcr function as potential enhancers and promote gene expression. However, lysine crotonylation in S. agalactiae has not been studied yet. Methods In this study, the crotonylation profiling of fish pathogen, S. agalactiae was investigated by combining affinity enrichment with LC MS/MS. The Kcr modification of several selected proteins were further validated by Western blotting. Results In the present study, we conducted the proteome-wide profiling of Kcr in S. agalactiae and identified 241 Kcr sites from 675 screened proteins for the first time. Bioinformatics analysis showed that 164 sequences were matched to a total of six definitively conserved motifs, and many of them were significantly enriched in metabolic processes, cellular process, and single-organism processes. Moreover, four crotonylation modified proteins were predicted as virulence factors or to being part of the quorum sensing system PTMs on bacteria. The data are available via ProteomeXchange with identifier PXD026445. Conclusions These data provide a promising starting point for further functional research of crotonylation in bacterial virulence in S. agalactiae.

Abstract
Lysine crotonylation (Kcr) is a newly discovered posttranslational modification (PTM), which has been studied at the proteomics level in a few species, with the study of Kcr in female fertility and in insect species is still lacking. Harmonia axyridis (Pallas) is a well-known beneficial insect used as a natural biological control agent against aphids in agriculture. Here, global Kcr identification in ovarian tissue of H. axyridis at diapause stage was performed to reveal potential roles for Kcr in H. axyridis ovarian cellular processes, female fertility and diapause regulation. In total, 3084 Kcr sites in 920 proteins were identified. Bioinformatic analyses revealed the distribution of these proteins in multiple subcellular localization categories and their involvement in diverse biological processes and metabolism pathways. Carbohydrate and energy metabolism related cellular processes including citric acid cycle, glycolysis and oxidative phosphorylation appeared be affected by Kcr modification. In addition, regulation of translation and protein biosynthesis may reflect Kcr involvement in diapause in H. axyridis, with Kcr affecting ribosome activities and amino acid metabolism. Moreover, Kcr modulation H. axyridis ovary development regulation may share some common mechanism with Kcr participation in some disease progression. These processes and pathways were uncovered under diapause stage, but possibly not enriched/specific for diapause stage due to limitations of qualitative proteomics experimental design. Our results informs on the potential for Kcr modifications to regulate female fertility and insect physiology.

Abstract
Genome regulation, temporal and spatial variations in cell function, continues to puzzle and interest life scientists who aim to unravel the molecular basis of human health and disease, not to mention plant biology and ecosystem diversity. Despite important advances in epigenomics and protein post-translational modifications over the past decade, there is a need for new conceptual lenses to understand biological mechanisms that can help unravel the fundamental regulatory questions in genomes and the cell. To these ends, lys crotonylation (Kcr) is a reversible protein modification catalyzed by protein crotonyl transferases and decrotonylases. First identified on histones, Kcr regulates cellular processes at the chromatin level. Research thus far has revealed that Kcr marks promoter sites of active genes and potential enhancers. Eventually, Kcr on a number of nonhistone proteins was reported. The abundance of Kcr on ribosomal and myofilament proteins indicates its functional roles in protein synthesis and muscle contraction. Kcr has also been associated with pluripotency, spermiogenesis, and DNA repair. In plants, large-scale mass spectrometry-based experiments validated the roles of Kcr in photosynthesis. In this expert review, we present the latest thinking and findings on lys crotonylation with an eye to regulation of cell biology. We discuss the enrichment techniques, putative biological functions, and challenges associated with studying this protein modification with vast biological implications. Finally, we reflect on the future outlook about the broader relevance of Kcr in animals, microbes, and plant species.

Abstract
Crotonylation is a kind of newly discovered acylation modification. Thousands of crotonylation sites have been identified in histone and non-histone proteins over the past decade. As a modification closely related to acetylation, crotonylation was reported to share many universal enzymes with acetylation. Crotonylated proteins have important roles in the regulation of various biological processes, such as gene expression, process of spermatogenesis, cell cycle, and also in the pathogenesis of different diseases, which range from depression to cancer. In this review, we summarize the research processes of crotonylation and discuss the advances of regulation mechanism of both histone and non-histone proteins crotonylation in difference physiological processes. Also, we focus on the alteration of the crotonylation under certain pathological conditions and its role in the pathogenesis of each disease.

Abstract
Lysine crotonylation has been discovered in histone and non-histone proteins and found to be involved in diverse diseases and biological processes, such as neuropsychiatric disease, carcinogenesis, spermatogenesis, tissue injury, and inflammation. The unique carbon–carbon π-bond structure indicates that lysine crotonylation may use distinct regulatory mechanisms from the widely studied other types of lysine acylation. In this review, we discussed the regulation of lysine crotonylation by enzymatic and non-enzymatic mechanisms, the recognition of substrate proteins, the physiological functions of lysine crotonylation and its cross-talk with other types of modification. The tools and methods for prediction and detection of lysine crotonylation were also described.

Abstract
Myzus persicae is one of the most important economic pests of cultivated crops. In the present study, we used an integrated approach involving high-performance liquid chromatography fractionation, affinity enrichment, and mass spectrometry-based proteomics to carry out a comprehensive proteomic analysis of lysine crotonylation in M. persicae. Altogether, 7530 lysine crotonylation sites were identified in 2452 protein groups. Intensive bioinformatic analyses were then carried out to annotate those lysine crotonylated targets identified in terms of Gene Ontology annotation, domain annotation, subcellular localization, Kyoto Encyclopedia of Genes and Genomes pathway annotation, functional cluster analysis, etc. Analysis results showed that lysine-crotonylated proteins were involved in many biological processes, such as the amino acid metabolism, aminoacyl-tRNA biosynthesis, spliceosomes, ribosomes, and so forth. Notably, the interaction network showed that there were 199 crotonylated proteins involved in the amino acid metabolism and numerous crotonylation targets associated with fatty acid biosynthesis and degradation. The results provide a system-wide view of the entire M. persicae crotonylome and a rich data set for functional analysis of crotonylated proteins in this economically important pest, which marks an important beginning for the further research.

Huang Q, Liao X, Yang X, Luo Y, Lin P, Zeng Q, Bai H, Jiang B, Pan Y, Zhang F, Zhang L, Jia Y, Liu Q. Lysine crotonylation of DgTIL1 at K72 modulates cold tolerance by enhancing DgnsLTP stability in chrysanthemum. PLANT BIOTECHNOLOGY JOURNAL 2021; 19:1125-1140. [PMID: 33368971 PMCID: PMC8196654 DOI: 10.1111/pbi.13533] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/04/2020] [Revised: 11/25/2020] [Accepted: 12/14/2020] [Indexed: 05/10/2023]
Abstract
Lysine crotonylation of proteins is a recently identified post-translational modification (PTM) in plants. However, the function of lysine-crotonylated proteins in response to abiotic stress in plants has not been reported. In this study, we identified a temperature-induced lipocalin-1-like gene (DgTIL1) from chrysanthemum and showed that it was notably induced in response to cold stress. Overexpression of DgTIL1 enhanced cold tolerance in transgenic chrysanthemum. Ubiquitin membrane yeast two-hybrid (MYTH) system and bimolecular fluorescence complementation (BIFC) assays showed that DgTIL1 interacts with a nonspecific lipid transfer protein (DgnsLTP), which can promote peroxidase (POD) gene expression and POD activity to reduce the accumulation of reactive oxygen species (ROS) and improve resistance to cold stress in DgnsLTP transgenic chrysanthemum. In addition, we found that DgTIL1 was lysine crotonylated at K72 in response to low temperature in chrysanthemum. Moreover, lysine crotonylation of DgTIL1 prevented DgnsLTP protein degradation in tobacco and chrysanthemum. Inhibition of DgnsLTP degradation by lysine crotonylation of DgTIL1 further enhanced POD expression and POD activity, reduced the accumulation of ROS under cold stress in DgTIL1 transgenic chrysanthemum, thus promoting the cold resistance of chrysanthemum.

Abstract
Crotonylation of proteins is a newly found type of post-translational modifications (PTMs) which occurs leadingly on the lysine residue, namely, lysine crotonylation (Kcr). Kcr is conserved and is regulated by a series of enzymes and co-enzymes including lysine crotonyltransferase (writer), lysine decrotonylase (eraser), certain YEATS proteins (reader), and crotonyl-coenzyme A (donor). Histone Kcr has been substantially studied since 2011, but the Kcr of non-histone proteins is just an emerging field since its finding in 2017. Recent advances in the identification and quantification of non-histone protein Kcr by mass spectrometry have increased our understanding of Kcr. In this review, we summarized the main proteomic characteristics of non-histone protein Kcr and discussed its biological functions, including gene transcription, DNA damage response, enzymes regulation, metabolic pathways, cell cycle, and localization of heterochromatin in cells. We further proposed the performance of non-histone protein Kcr in diseases and the prospect of Kcr manipulators as potential therapeutic candidates in the diseases.

Front Microbiol 2021; 12:630694.

Abstract
Different types of post-translational modifications are present in bacteria that play essential roles in bacterial metabolism modulation. Nevertheless, limited information is available on these types of modifications in actinobacteria, particularly on their effects on secondary metabolite biosynthesis. Recently, phosphorylation, acetylation, or phosphopantetheneylation of transcriptional factors and key enzymes involved in secondary metabolite biosynthesis have been reported. There are two types of phosphorylations involved in the control of transcriptional factors: (1) phosphorylation of sensor kinases and transfer of the phosphate group to the receiver domain of response regulators, which alters the expression of regulator target genes. (2) Phosphorylation systems involving promiscuous serine/threonine/tyrosine kinases that modify proteins at several amino acid residues, e.g., the phosphorylation of the global nitrogen regulator GlnR. Another post-translational modification is the acetylation at the epsilon amino group of lysine residues. The protein acetylation/deacetylation controls the activity of many short and long-chain acyl-CoA synthetases, transcriptional factors, key proteins of bacterial metabolism, and enzymes for the biosynthesis of non-ribosomal peptides, desferrioxamine, streptomycin, or phosphinic acid-derived antibiotics. Acetyltransferases catalyze acetylation reactions showing different specificity for the acyl-CoA donor. Although it functions as acetyltransferase, there are examples of malonylation, crotonylation, succinylation, or in a few cases acylation activities using bulky acyl-CoA derivatives. Substrates activation by nucleoside triphosphates is one of the central reactions inhibited by lysine acetyltransferases. Phosphorylation/dephosphorylation or acylation/deacylation reactions on global regulators like PhoP, GlnR, AfsR, and the carbon catabolite regulator glucokinase strongly affects the expression of genes controlled by these regulators. Finally, a different type of post-translational protein modification is the phosphopantetheinylation, catalized by phosphopantetheinyl transferases (PPTases). This reaction is essential to modify those enzymes requiring phosphopantetheine groups like non-ribosomal peptide synthetases, polyketide synthases, and fatty acid synthases. Up to five PPTases are present in S. tsukubaensis and S. avermitilis. Different PPTases modify substrate proteins in the PCP or ACP domains of tacrolimus biosynthetic enzymes. Directed mutations of genes encoding enzymes involved in the post-translational modification is a promising tool to enhance the production of bioactive metabolites.

Abstract
Lysine crotonylation (Kcr) is an evolutionally conserved post-translational modification (PTM) on histone proteins. However, information about Kcr and its involvement in the biology and metabolism of Toxoplasma gondii is limited. In the present study, a global Kcr proteome analysis using LC-MS/MS in combination with immune-affinity method was performed. A total of 12,152 Kcr sites distributed over 2719 crotonylated proteins were identified. Consistent with lysine acetylation and succinylation in Apicomplexa, Kcr was associated with various metabolic pathways, including carbon metabolism, pyrimidine metabolism, glycolysis, gluconeogenesis, and proteasome. Markedly, many stage-specific proteins, histones, and histone-modifying enzymes related to the stage transition were found to have Kcr sites, suggesting a potential involvement of Kcr in the parasite stage transformation. Most components of the apical secretory organelles were identified as crotonylated proteins which were associated with the attachment, invasion, and replication of T. gondii. These results expanded our understanding of Kcr proteome and proposed new hypotheses for further research of the Kcr roles in the pathobiology of T. gondii infection.

Abstract
Lysine crotonylation is an important post-translational modification process. Most research in this area has been carried out on mammals and yeast, but there has been little research on it in plants. In the current study, large-scale lysine crotonylome analysis was performed by a combination of affinity enrichment and high-resolution LC-MS/MS analysis. Altogether, 6051 lysine crotonylation sites were identified in 2508 protein groups. Bioinformatics analysis showed that lysine-crotonylated proteins were involved in many biological processes, such as carbon fixation in photosynthetic organisms, biosynthesis of amino acids, ribosomes structure and function. In particular, subcellular localization analysis showed that 43% of the crotonylated proteins were located in the chloroplast. Twenty-nine crotonylation proteins were associated with photosynthesis and functional enrichment that these proteins were associated with the reaction center, photosynthetic electron transport, and ATP synthesis. Based on these results, further studies to expand on the lysine crotonylome analysis were suggested.

Abstract
Histone crotonylation is a recently described post-translational modification that occurs at multiple identified histone lysine crotonylation sites. An increasing number of studies have demonstrated that histone crotonylation at DNA regulatory elements plays an important role in the activation of gene transcription. However, among others, we have shown that elevated cellular crotonylation levels result in the inhibition of endocytosis-related gene expression and pro-growth gene expression, implicating the complexity of histone crotonylation in gene regulation. Therefore, it is important to understand how histone crotonylation is regulated and how it, in turn, regulates the expression of its target genes. In this review, we summarize the regulatory factors that control histone crotonylation and discuss the role of different histone crotonylation sites in regulating gene expression, while providing novel insights into the central role of histone crotonylation in gene regulation.

Abstract
BACKGROUND Low-temperature severely affects the growth and development of chrysanthemum which is one kind of ornamental plant well-known and widely used in the world. Lysine crotonylation is a recently identified post-translational modification (PTM) with multiple cellular functions. However, lysine crotonylation under low-temperature stress has not been studied. RESULTS Proteome-wide and lysine crotonylation of chrysanthemum at low-temperature was analyzed using TMT (Tandem Mass Tag) labeling, sensitive immuno-precipitation, and high-resolution LC-MS/MS. The results showed that 2017 crotonylation sites were identified in 1199 proteins. Treatment at 4 °C for 24 h and - 4 °C for 4 h resulted in 393 upregulated proteins and 500 downregulated proteins (1.2-fold threshold and P < 0.05). Analysis of biological information showed that lysine crotonylation was involved in photosynthesis, ribosomes, and antioxidant systems. The crotonylated proteins and motifs in chrysanthemum were compared with other plants to obtain orthologous proteins and conserved motifs. To further understand how lysine crotonylation at K136 affected APX (ascorbate peroxidase), we performed a site-directed mutation at K136 in APX. Site-directed crotonylation showed that lysine decrotonylation at K136 reduced APX activity, and lysine complete crotonylation at K136 increased APX activity. CONCLUSION In summary, our study comparatively analyzed proteome-wide and crotonylation in chrysanthemum under low-temperature stress and provided insights into the mechanisms of crotonylation in positively regulated APX activity to reduce the oxidative damage caused by low-temperature stress. These data provided an important basis for studying crotonylation to regulate antioxidant enzyme activity in response to low-temperature stress and a new research ideas for chilling-tolerance and freezing-tolerance chrysanthemum molecular breeding.

Abstract
Previous research has shown that the extracts from the Ganoderma lucidum spore (GS) have potentially cardioprotective effects, but there is still abundant room for development in determining its mechanism. In this study, the rat model of cardiac dysfunction was established by intraperitoneal injection of trimethylamine-N-oxide (TMAO), and the extracts of GS (oil, lipophilic components, and polysaccharides) were given intragastrically at a dose of 50 mg/kg/day to screen the pharmacological active components of GS. After 50 days of treatments, we found that the extraction from GS reduced the levels of total cholesterol, triglyceride, and low-density lipoprotein; increased the levels of high-density lipoprotein; and reduced the levels of serum TMAO when compared to the model group (P < 0.05); especially the GS polysaccharides (DT) and GS lipophilic components (XF) exhibited decreases in serum TMAO compared to TMAO-induced control. The results of 16S rRNA sequencing showed that GS could change the gut microbiota, increasing the abundance of Firmicutes and Proteobacteria in the DT-treated group and XF-treated group, while reducing the abundance of Actinobacteria and Tenericutes. Quantitative proteomics analysis showed that GS extracts (DT and XF) could regulate the expression of some related proteins, such as Ucp1 (XF-TMAO/M-TMAO ratio is 2.76), Mpz (8.52), Fasn (2.39), Nefl (1.85), Mtnd5 (0.83), Mtnd2 (0.36), S100a8 (0.69), S100a9 (0.70), and Bdh1 (0.72). The results showed that XF can maintain the metabolic balance and function of the heart by regulating the expression of some proteins related to cardiovascular disease, and DT can reduce the risk of cardiovascular diseases by targeting gut microbiota.

Abstract
Lysine crotonylation (Kcr), a recently discovered post-translational modification, plays a key role in the regulation of diverse cellular processes. Botrytis cinerea is a destructive necrotrophic fungal pathogen distributed worldwide with broad ranging hosts. However, the functions of Kcr are unknown in B. cinerea or any other plant fungal pathogens. Here, we comprehensively evaluated the crotonylation proteome of B. cinerea and identified 3967 Kcr sites in 1041 proteins, which contained 9 types of modification motifs. Our results show that although the crotonylation was largely conserved, different organisms contained distinct crotonylated proteins with unique functions. Bioinformatics analysis demonstrated that the majority of crotonylated proteins were distributed in cytoplasm (35%), mitochondria (26%), and nucleus (22%). The identified proteins were found to be involved in various metabolic and cellular processes, such as cytoplasmic translation and structural constituent of ribosome. Particularly, 26 crotonylated proteins participated in the pathogenicity of B. cinerea, suggesting a significant role for Kcr in this process. Protein interaction network analysis demonstrated that many protein interactions are regulated by crotonylation. Furthermore, our results show that different nutritional conditions had a significant influence on the Kcr levels of B. cinerea. These data represent the first report of the crotonylome of B. cinerea and provide a good foundation for further explorations of the role of Kcr in plant fungal pathogens.

[PMID: 33057814 DOI: 10.1007/s00436-020-06923-w] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2020] [Accepted: 10/06/2020] [Indexed: 11/28/2022]
Abstract
Lysine 2-hydroxyisobutyrylation (Khib) is a recently discovered and evolutionarily conserved form of protein post-translational modification (PTM) found in mammalian and yeast cells. Previous studies have shown that Khib plays roles in the activity of gene transcription and Khib-containing proteins are closely related to the cellular metabolism. In this study, a global Khib-containing analysis using the latest databases (ToxoDB 46, 8322 sequences, downloaded on April 16, 2020) and sensitive immune-affinity enrichment coupled with liquid chromatography-tandem mass spectrometry was performed. A total of 1078 Khib modification sites across 400 Khib-containing proteins were identified in tachyzoites of Toxoplasma gondii RH strain. Bioinformatics and functional enrichment analysis showed that Khib-modified proteins were associated with various biological processes, such as ribosome, glycolysis/gluconeogenesis, and central carbon metabolism. Interestingly, many proteins of the secretory organelles (e.g., microneme, rhoptry, and dense granule) that play roles in the infection cycle of T. gondii were found to be Khib-modified, suggesting the involvement of Khib in key biological process during T. gondii infection. We also found that histone proteins, key enzymes related to cellular metabolism, and several glideosome components had Khib sites. These results expanded our understanding of the roles of Khib in T. gondii and should promote further investigations of how Khib regulates gene expression and key biological functions in T. gondii.

Abstract
The gene expression is tightly regulated temporally and spatially to ensure the plant and animal proper development, function, growth, and survival under different environmental conditions. Chromatin regulation plays a central role in the gene expression by providing transcription factors and the transcription machinery with dynamic access to an otherwise tightly packaged genome. In this review, we will summarize recent progress in understanding the roles of chromatin regulation in the gene expression, and their contribution to the plant hormone and stress responses. We highlight the most recent publications within this topic and underline the roles of chromatin regulation in gene expression.

Abstract
Lysine ubiquitination, a widely studied posttranslational modification, plays vital roles in various biological processes in eukaryotic cells. Although several studies have examined the plant ubiquitylome, no such research has been performed in tobacco, a model plant for molecular biology. Here, we comprehensively analyzed lysine ubiquitination in tobacco (Nicotiana tabacum) using LC-MS/MS along with highly sensitive immune-affinity purification. In total, 964 lysine-ubiquitinated (Kub) sites were identified in 572 proteins. Extensive bioinformatics studies revealed the distribution of these proteins in various cellular locations, including the cytoplasm, chloroplast, nucleus, and plasma membrane. Notably, 25% of the Kub proteins were located in the chloroplast of which 21 were enzymatically involved in important pathways, that is, photosynthesis and carbon fixation. Western blot analysis indicated that TMV infection can cause changes in ubiquitination levels. This is the first comprehensive proteomic analysis of lysine ubiquitination in tobacco, illustrating the vital role of ubiquitination in various physiological and biochemical processes and representing a valuable addition to the existing landscape of lysine ubiquitination.

Large-scale lysine crotonylation analysis reveals its potential role in spermiogenesis in the Chinese mitten crab Eriocheir sinensis. J Proteomics 2020; 226:103891. [PMID: 32629196 DOI: 10.1016/j.jprot.2020.103891] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2019] [Revised: 03/15/2020] [Accepted: 06/26/2020] [Indexed: 11/24/2022]
Abstract
Lysine crotonylation (Kcr) is a recently-discovered type of post-translational modification. Although Kcr has been reported in many species, little is known about this process in crustaceans. In this study, pan anti-lysine crotonylation antibody enrichment and high-resolution liquid chromatogram-mass spectrometry analysis were employed to characterize Kcr in testis of the Chinese mitten crab Eriocheir sinensis testis. Overall, 2799 Kcr sites were identified on 908 proteins with 14 conserved motifs. Bioinformatics analysis showed that Kcr was predominant on proteins found in cytoplasm, mitochondria and nucleus, and those involved in ribosome, proteasome, carbon metabolism and protein processing in endoplasmic reticulum. In total, 83 up-regulated and 12 down-regulated non-histone crotonylated sites were identified during spermiogenesis. These differentially expressed proteins were enriched in protein processing in endoplasmic reticulum pathway during formation of acrosome. In contrast, histone Kcr associated with mammalian spermatogenesis. These results provide foundational knowledge on the role of non-histone Kcr in spermiogenesis of E. sinensis. SIGNIFICANCE: Lysine crotonylation (Kcr) is a recently-identified post-translational modification, and histone Kcr was found to associate with mammalian spermatogenesis. However, crotonylation of non-histone proteins has not been reported in spermatogenesis regulation. Further, there is no information on crotonylation in crustaceans. This study was the first large-scale Kcr proteome characterization in crustaceans. A total of 2799 Kcr sites on 908 proteins with 14 conserved motifs were identified from Eriocheir sinensis testis. Of which, 83 up-regulated and 12 down-regulated non-histone crotonylated sites were identified during spermiogenesis. Our results provide the basic information for further functional validation of Kcr proteins and revealed new roles of Kcr in spermiogenesis of E. sinensis.

Abstract
BACKGROUND Lysine 2-hydroxyisobutyrylation (Khib), a newly identified post-translational modification, is known to regulate transcriptional activity in animals. However, extensive studies of the lysine 2-hydroxyisobutyrylome in plants and animals have yet to be performed. RESULTS In this study, using LC-MS/MS qualitative proteomics strategies, we identified 4163 Khib sites on 1596 modified proteins in rice (Oryza sativa) seedlings. Motif analysis revealed 10 conserved motifs flanking the Khib sites, and subcellular localization analysis revealed that 44% of the Khib proteins are localized in the chloroplast. Gene ontology function, KEGG pathway, and protein domain enrichment analyses revealed that Khib occurs on proteins involved in diverse biological processes and is especially enriched in carbon metabolism and photosynthesis. Among the modified proteins, 20 Khib sites were identified in histone H2A and H2B, while only one site was identified in histone H4. Protein-protein interaction (PPI) network analysis further demonstrated that Khib participates in diverse biological processes including ribosomal activity, biosynthesis of secondary metabolites, and metabolic pathways. In addition, a comparison of lysine 2-hydroxyisobutyrylation, acetylation, and crotonylation in the rice proteome showed that 45 proteins with only 26 common lysine sites are commonly modified by three PTMs. The crosstalk of modified sites and PPI among these PTMs may form a complex network with both similar and different regulatory mechanisms. CONCLUSIONS In summary, our study comprehensively profiles the lysine 2-hydroxyisobutyrylome in rice and provides a better understanding of its biological functions in plants.

Crotonylation of key metabolic enzymes regulates carbon catabolite repression in Streptomyces roseosporus. Commun Biol 2020; 3:192.

Abstract
Due to the plethora natural products made by Streptomyces, the regulation of its metabolism are of great interest, whereas there is a lack of detailed understanding of the role of posttranslational modifications (PTM) beyond traditional transcriptional regulation. Herein with Streptomyces roseosporus as a model, we showed that crotonylation is widespread on key enzymes for various metabolic pathways, and sufficient crotonylation in primary metabolism and timely elimination in secondary metabolism are required for proper Streptomyces metabolism. Particularly, the glucose kinase Glk, a keyplayer of carbon catabolite repression (CCR) regulating bacterial metabolism, is identified reversibly crotonylated by the decrotonylase CobB and the crotonyl-transferase Kct1 to negatively control its activity. Furthermore, crotonylation positively regulates CCR for Streptomyces metabolism through modulation of the ratio of glucose uptake/Glk activity and utilization of carbon sources. Thus, our results revealed a regulatory mechanism that crotonylation globally regulates Streptomyces metabolism at least through positive modulation of CCR. Chen-Fan Sun et al. show that key enzymes in several metabolic pathways are crotonylated in Streptomyces roseosporus. This study suggests that crotonylation increases carbon catabolite repression by increasing glucose uptake while reducing the activity of glucose kinase.

Abstract
Chloroplast, the photosynthetic machinery, converts photoenergy to ATP and NADPH, which powers the production of carbohydrates from atmospheric CO2 and H2O. It also serves as a major production site of multivariate pro-defense molecules, and coordinate with other organelles for cell defense. Chloroplast harbors 30-50% of total cellular proteins, out of which 80% are membrane residents and are difficult to solubilize. While proteome profiling has illuminated vast areas of biological protein space, a great deal of effort must be invested to understand the proteomic landscape of the chloroplast, which plays central role in photosynthesis, energy metabolism and stress-adaptation. Therefore, characterization of chloroplast proteome would not only provide the foundation for future investigation of expression and function of chloroplast proteins, but would open up new avenues for modulation of plant productivity through synchronizing chloroplastic key components. In this review, we summarize the progress that has been made to build new understanding of the chloroplast proteome and implications of chloroplast dynamicsing generate metabolic energy and modulating stress adaptation.

Abstract
Toxoplasma gondii is a unicellular protozoan parasite of the phylum Apicomplexa. The parasite repeatedly goes through a cycle of invasion, division and induction of host cell rupture, which is an obligatory process for proliferation inside warm-blooded animals. It is known that the biology of the parasite is controlled by a variety of mechanisms ranging from genomic to epigenetic to transcriptional regulation. In this study, we investigated the global protein posttranslational lysine crotonylation and 2-hydroxyisobutyrylation of two T. gondii strains, RH and ME49, which represent distinct phenotypes for proliferation and pathogenicity in the host. Proteins with differential expression and modification patterns associated with parasite phenotypes were identified. Many proteins in T. gondii were crotonylated and 2-hydroxyisobutyrylated, and they were localized in diverse subcellular compartments involved in a wide variety of cellular functions such as motility, host invasion, metabolism and epigenetic gene regulation. These findings suggest that lysine crotonylation and 2-hydroxyisobutyrylation are ubiquitous throughout the T. gondii proteome, regulating critical functions of the modified proteins. These data provide a basis for identifying important proteins associated with parasite development and pathogenicity.

Abstract
Lysine crotonylation is a newly discovered post‐translational modification, which is structurally and functionally different from the widely studied lysine acetylation. Recent advances in the identification and quantification of lysine crotonylation by mass spectrometry have revealed that non‐histone proteins are frequently crotonylated, implicating it in many biological processes through the regulation of chromatin remodelling, metabolism, cell cycle and cellular organization. In this review, we summarize the writers, erasers and readers of lysine crotonylation, and their physiological functions, including gene transcription, acute kidney injury, spermatogenesis, depression, telomere maintenance, HIV latency and cancer process. These findings not only point to the new functions for lysine crotonylation, but also highlight the mechanisms by which crotonylation regulates various cellular processes.

However, identification of the pathological mechanisms underlying these abnormal neuroanatomical structures in the brains of BTBR mice is still lacking. Posttranslational modifications (PTMs) are known to be involved in the regulation of diverse cellular processes, and evidence shows that some types of PTMs are associated with the development of the central nervous system. In this study, we detected four novel PTMs in the cerebral cortex of BTBR mice as compared to C57BL/6 J (B6) mice using western blotting. Results revealed that lysine crotonylation and succinylation were elevated in the cerebral cortex of BTBR mice compared to levels in B6 mice. We speculate that elevated profiles of lysine crotonylation and succinylation may be involved in mechanisms related to neuroanatomical abnormalities in cerebral cortex of BTBR mice.

[PMID: 31060518 PMCID: PMC6501322 DOI: 10.1186/s12864-019-5716-z] [Citation(s) in RCA: 27] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2018] [Accepted: 04/18/2019] [Indexed: 12/21/2022] Open
Abstract
BACKGROUND Lysine crotonylation, as a novel evolutionarily conserved type of post-translational modifications, is ubiquitous and essential in cell biology. However, its functions in tea plants are largely unknown, and the full functions of lysine crotonylated proteins of tea plants in nitrogen absorption and assimilation remains unclear. Our study attempts to describe the global profiling of nonhistone lysine crotonylation in tea leaves and to explore how ammonium (NH4+) triggers the response mechanism of lysine crotonylome in tea plants. RESULTS Here, we performed the global analysis of crotonylome in tea leaves under NH4+ deficiency/resupply using high-resolution LC-MS/MS coupled with highly sensitive immune-antibody. A total of 2288 lysine crotonylation sites on 971 proteins were identified, of which contained in 15 types of crotonylated motifs. Most of crotonylated proteins were located in chloroplast (37%) and cytoplasm (33%). Compared with NH4+ deficiency, 120 and 151 crotonylated proteins were significantly changed at 3 h and 3 days of NH4+ resupply, respectively. Bioinformatics analysis showed that differentially expressed crotonylated proteins participated in diverse biological processes such as photosynthesis (PsbO, PsbP, PsbQ, Pbs27, PsaN, PsaF, FNR and ATPase), carbon fixation (rbcs, rbcl, TK, ALDO, PGK and PRK) and amino acid metabolism (SGAT, GGAT2, SHMT4 and GDC), suggesting that lysine crotonylation played important roles in these processes. Moreover, the protein-protein interaction analysis revealed that the interactions of identified crotonylated proteins diversely involved in photosynthesis, carbon fixation and amino acid metabolism. Interestingly, a large number of enzymes were crotonylated, such as Rubisco, TK, SGAT and GGAT, and their activities and crotonylation levels changed significantly by sensing ammonium, indicating a potential function of crotonylation in the regulation of enzyme activities. CONCLUSIONS The results indicated that the crotonylated proteins had a profound influence on metabolic process of tea leaves in response to NH4+ deficiency/resupply, which mainly involved in diverse aspects of primary metabolic processes by sensing NH4+, especially in photosynthesis, carbon fixation and amino acid metabolism. The data might serve as important resources for exploring the roles of lysine crotonylation in N metabolism of tea plants. Data were available via ProteomeXchange with identifier PXD011610.

[PMID: 30233516 PMCID: PMC6129574 DOI: 10.3389/fmicb.2018.02025] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2018] [Accepted: 08/09/2018] [Indexed: 12/26/2022] Open
Abstract
Patulin (PAT) is a mycotoxin produced by some Penicillium, Aspergillus, and Byssochlamys species. Rhodotorula mucilaginosa is able to degrade PAT in vivo as well as in vitro, up till date, the process and molecular mechanism(s) involved patulin degradation still remains unknown. Protein lysine crotonylation (Kcr) plays an important role in regulating chromatin dynamics, gene expression, and metabolic pathways in mammals and eukaryotes. Investigation of the Kcr changes accompanying degradation of patulin in R. mucilaginosa were observed to investigate the mechanisms of patulin inhibition. Tandem mass tag (TMT) labeling and Kcro affinity enrichment, followed by high-resolution LC-MS/MS analysis, were used to perform quantitative lysine crotonylome analysis on R. mucilaginosa. Consequently, 1691 lysine crotonylation sites in 629 protein groups were identified, among which we quantified 1457 sites in 562 proteins. Among the quantified proteins, 79 and 46 crotonylated proteins were up-regulated and down-regulated, respectively. The differentially up expressed modified proteins were mainly involved in tricarboxylic acid cycle and gluconeogenic pathway. The differentially down expressed Kcr proteins were mainly classified to ribosome and carbohydrate transport and metabolism. Bioinformatic analyses were performed to annotate the quantifiable lysine crotonylated targets. Moreover, interaction networks and high confidence domain architectures of crotonylated proteins were investigated with the aid of bioinformatic tools, and these results showed that there was an increase in the number of yeasts with crotonylated proteins. The results also provided information on the various roles of crotonylation, which are involved in PAT degradation.

Abstract
The analysis of the post-translational modification (PTM) state of proteins using mass spectrometry-based bottom-up proteomic workflows has evolved into a powerful tool for the study of cellular regulatory events that are not directly encoded at the genome level. Besides frequently detected modifications such as phosphorylation, acetylation and ubiquitination, many low abundant or less frequently detected PTMs are known or postulated to serve important regulatory functions. To more broadly understand the LC-MS/MS characteristics of PTMs, we synthesized and analyzed ∼5,000 peptides representing 21 different naturally occurring modifications of lysine, arginine, proline and tyrosine side chains and their unmodified counterparts. The analysis identified changes in retention times, shifts of precursor charge states and differences in search engine scores between modifications. PTM-dependent changes in the fragmentation behavior were evaluated using eleven different fragmentation modes or collision energies. We also systematically investigated the formation of diagnostic ions or neutral losses for all PTMs, confirming 10 known and identifying 5 novel diagnostic ions for lysine modifications. To demonstrate the value of including diagnostic ions in database searching, we reprocessed a public data set of lysine crotonylation and showed that considering the diagnostic ions increases confidence in the identification of the modified peptides. To our knowledge, this constitutes the first broad and systematic analysis of the LC-MS/MS properties of common and rare PTMs using synthetic peptides, leading to direct applicable utility for bottom-up proteomic experiments.
