JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY 2023; 71:14825-14837. [PMID: 37792446 PMCID: PMC10591476 DOI: 10.1021/acs.jafc.3c00886] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/16/2023] [Revised: 09/07/2023] [Accepted: 09/12/2023] [Indexed: 10/05/2023]
Abstract
Post-translational modifications (PTMs) of biomacromolecules can be useful for understanding the processes by which a relatively small number of individual genes in a particular genome can generate enormous biological complexity in different organisms. The proteomes of barley and the brewing process were investigated by different techniques. However, their diverse and complex PTMs remain understudied. As standard analytical approaches have limitations, innovative analytical approaches need to be developed and applied in PTM studies. To make further progress in this field, it is necessary to specify the sites of modification, as well as to characterize individual isoforms with increased selectivity and sensitivity. This review summarizes advances in the PTM analysis of barley proteins, particularly those involving mass spectrometric detection. Our focus is on monitoring phosphorylation, glycation, and glycosylation, which critically influence functional behavior in metabolism and regulation in organisms.

Protein Expr Purif 2023; 205:106244.

Abstract
In the present study, an engineered interleukin-2 (IL-2) fusion protein consisting of an anti-human serum albumin nanobody linked by ASTKG and a (G4S)2 linker to IL-2 was constructed. Liquid chromatography-mass spectrometry (LC-MS) characterization was performed on the intact molecule and at the peptide level. The LC-MS molecular mass analysis for the engineered fusion protein showed the appearance of unreported +340 Da peaks, apart from the expected O-glycosylation-related peaks in the IL-2 domain. Through a combination analysis of a K120R mutated molecule (The lysine at the position of 120 was mutated to arginine while the rest amino acid sequence remain unchanged), the possibility of a non-cleaved valine-histidine-serine signal peptide was ruled out and the presence of hydroxylysine (HyK) O-glycosylation in the ASTKG linker was confirmed. HyK O-glycosylation have been reported in other proteins such as collagen, which occurs in the conserved Gly-Xaa-HyK motif and is catalyzed by lysyl hydroxylase-3 complex. The present study showed high similar conserved motif of HyK-O-glycosylation in collagen, implying the HyK O-glycosylation in the engineered IL-2 possibly was catalyzed by the Chinese hamster ovary homolog of enzymes promoting HyK O-glycosylation in collagen. Bioactivity testing results revealed that HyK-O-glycosylation had no obvious effect on the in vitro activity of engineered IL-2. Our study is the first to report HyK-O-glycosylation modifications in therapeutic proteins through LC-MS characterization and in vitro activity analysis, which expands the scope of post-translational modification knowledge of therapeutic proteins.

Abstract
The extracellular matrix (ECM) plays an important role in lung health and disease. Collagen is the main component of the lung ECM, widely used for the establishment of in vitro and organotypic models of lung disease, and as scaffold material of general interest for the field of lung bioengineering. Collagen also is the main readout for fibrotic lung disease, where collagen composition and molecular properties are drastically changed and ultimately result in dysfunctional "scarred" tissue. Because of the central role of collagen in lung disease, quantification, determination of molecular properties, and three-dimensional visualization of collagen is important for both development and characterization of translational models of lung research. In this chapter, we provide a comprehensive overview on the various methodologies currently available for quantification and characterization of collagen including their detection principles, advantages, and disadvantages.

Abstract
INTRODUCTION Trimeric intracellular potassium channels TRIC-A and -B are endoplasmic reticulum (ER) integral membrane proteins, involved in the regulation of calcium release mediated by ryanodine (RyRs) and inositol 1,4,5-trisphosphate (IP3Rs) receptors, respectively. While TRIC-A is mainly expressed in excitable cells, TRIC-B is ubiquitously distributed at moderate level. TRIC-B deficiency causes a dysregulation of calcium flux from the ER, which impacts on multiple collagen specific chaperones and modifying enzymatic activity, leading to a rare form of osteogenesis imperfecta (OI Type XIV). The relevance of TRIC-B on cell homeostasis and the molecular mechanism behind the disease are still unknown. RESULTS In this study, we exploited zebrafish to elucidate the role of TRIC-B in skeletal tissue. We demonstrated, for the first time, that tmem38a and tmem38b genes encoding Tric-a and -b, respectively are expressed at early developmental stages in zebrafish, but only the latter has a maternal expression. Two zebrafish mutants for tmem38b were generated by CRISPR/Cas9, one carrying an out of frame mutation introducing a premature stop codon (tmem38b-/- ) and one with an in frame deletion that removes the highly conserved KEV domain (tmem38bΔ120-7/Δ120-7 ). In both models collagen type I is under-modified and partially intracellularly retained in the endoplasmic reticulum, as described in individuals affected by OI type XIV. Tmem38b-/- showed a mild skeletal phenotype at the late larval and juvenile stages of development whereas tmem38bΔ120-7/Δ120-7 bone outcome was limited to a reduced vertebral length at 21 dpf. A caudal fin regeneration study pointed towards impaired activity of osteoblasts and osteoclasts associated with mineralization impairment. DISCUSSION Our data support the requirement of Tric-b during early development and for bone cell differentiation.

Abstract
Bone fragility fractures remain an important worldwide health and economic problem due to increased morbidity and mortality. The current methods for predicting fractures are largely based on the measurement of bone mineral density and the utilization of mathematical risk calculators based on clinical risk factors for bone fragility. Despite these approaches, many bone fractures remain undiagnosed. Therefore, current research is focused on the identification of new factors such as bone turnover markers (BTM) for risk calculation. BTM are a group of proteins and peptides released during bone remodeling that can be found in serum or urine. They derive from bone resorptive and formative processes mediated by osteoclasts and osteoblasts, respectively. Potential use of BTM in monitoring these phenomenon and therefore bone fracture risk is limited by physiologic and pathophysiologic factors that influence BTM. These limitations in predicting fractures explain why their inclusion in clinical guidelines remains limited despite the large number of studies examining BTM.

Abstract
Fibrillar type I collagen is the most abundant structural protein in most tissues and organs. One of the unique and functionally important characteristics of collagen is sequential posttranslational modifications of lysine (Lys) residues. In the endoplasmic reticulum, hydroxylation of specific Lys occurs producing 5-hydroxylysine (Hyl). Then, to the 5-hydroxyl group of Hyl, a single galactose unit can be attached to form galactosyl-Hyl (Gal-Hyl) and further glucose can be added to Gal-Hyl to form glucosylgalactosyl-Hyl (GlcGal-Hyl). These are the only two O-linked glycosides found in mature type I collagen. It has been shown that this modification is critically involved in a number of biological and pathological processes likely through its regulatory roles in collagen fibrillogenesis, intermolecular cross-linking, and collagen-cell interaction. Recently, with the advances in molecular/cell biology and analytical chemistry, the molecular mechanisms of collagen glycosylation have been gradually deciphered, and the type and extent of glycosylation at the specific molecular loci can now be quantitatively analyzed. In this chapter, we describe quantitative analysis of collagen glycosylation by high-performance liquid chromatography (HPLC) and semiquantitative, site-specific analysis by HPLC-tandem mass spectrometry.

Abstract
Tryptic peptide mapping analysis of a Chinese hamster ovary (CHO)-expressed, recombinant IgG1 monoclonal antibody revealed a previously unreported +16 Da modification. Through a combination of MS(n) experiments, and preparation and analysis of known synthetic peptides, the possibility of a sequence variant (Ala to Ser) was ruled out and the presence of hydroxylysine was confirmed. Post-translational hydroxylation of lysine was found in a consensus sequence (XKG) known to be the site of modification in other proteins such as collagen, and was therefore presumed to result from the activity of the CHO homolog of the lysyl hydroxylase complex. Although this consensus sequence was present in several locations in the antibody sequence, only a single site on the heavy-chain Fab was found to be modified.

Abstract
Collagen IV is the main structural protein that provides a scaffold for assembly of basement membrane proteins. Posttranslational modifications such as hydroxylation of proline and lysine and glycosylation of lysine are essential for the functioning of collagen IV triple-helical molecules. These modifications are highly abundant posing a difficult challenge for in-depth characterization of collagen IV using conventional proteomics approaches. Herein, we implemented an integrated pipeline combining high-resolution mass spectrometry with different fragmentation techniques and an optimized bioinformatics workflow to study posttranslational modifications in mouse collagen IV. We achieved 82% sequence coverage for the α1 chain, mapping 39 glycosylated hydroxylysine, 148 4-hydroxyproline, and seven 3-hydroxyproline residues. Further, we employed our pipeline to map the modifications on human collagen IV and achieved 85% sequence coverage for the α1 chain, mapping 35 glycosylated hydroxylysine, 163 4-hydroxyproline, and 14 3-hydroxyproline residues. Although lysine glycosylation heterogeneity was observed in both mouse and human, 21 conserved sites were identified. Likewise, five 3-hydroxyproline residues were conserved between mouse and human, suggesting that these modification sites are important for collagen IV function. Collectively, these are the first comprehensive maps of hydroxylation and glycosylation sites in collagen IV, which lay the foundation for dissecting the key role of these modifications in health and disease.

Abstract
The proteomic analysis of glycosylation is uniquely challenging. The numerous and varied biological roles of protein-linked glycans have fueled a tremendous demand for technologies that enable rapid, in-depth structural examination of glycosylated proteins in complex biological systems. In turn, this demand has driven many innovations in wide ranging fields of bioanalytical science. This review will summarize key developments in glycoprotein separation and enrichment, glycoprotein proteolysis strategies, glycopeptide separation and enrichment, the role of mass measurement accuracy in glycopeptide detection, glycopeptide ion dissociation methods for MS/MS, and informatic tools for glycoproteomic analysis. In aggregate, this selection of topics serves to encapsulate the present status of MS-based analytical technologies for engaging the challenges of glycoproteomic analysis.

Abstract
Fibrillar type I collagen is the major organic component in bone, providing a stable template for mineralization. During collagen biosynthesis, specific hydroxylysine residues become glycosylated in the form of galactosyl- and glucosylgalactosyl-hydroxylysine. Furthermore, key glycosylated hydroxylysine residues, α1/2-87, are involved in covalent intermolecular cross-linking. Although cross-linking is crucial for the stability and mineralization of collagen, the biological function of glycosylation in cross-linking is not well understood. In this study, we quantitatively characterized glycosylation of non-cross-linked and cross-linked peptides by biochemical and nanoscale liquid chromatography-high resolution tandem mass spectrometric analyses. The results showed that glycosylation of non-cross-linked hydroxylysine is different from that involved in cross-linking. Among the cross-linked species involving α1/2-87, divalent cross-links were glycosylated with both mono- and disaccharides, whereas the mature, trivalent cross-links were primarily monoglycosylated. Markedly diminished diglycosylation in trivalent cross-links at this locus was also confirmed in type II collagen. The data, together with our recent report (Sricholpech, M., Perdivara, I., Yokoyama, M., Nagaoka, H., Terajima, M., Tomer, K. B., and Yamauchi, M. (2012) Lysyl hydroxylase 3-mediated glucosylation in type I collagen: molecular loci and biological significance. J. Biol. Chem. 287, 22998-23009), indicate that the extent and pattern of glycosylation may regulate cross-link maturation in fibrillar collagen.

Abstract
The most abundant proteins in vertebrates - the collagen family proteins - play structural and biological roles in the body. The predominant member, type I collagen, provides tissues and organs with structure and connectivity. This protein has several unique post-translational modifications that take place intra- and extra-cellularly. With growing evidence of the relevance of such post-translational modifications in health and disease, the biological significance of O-linked collagen glycosylation has recently drawn increased attention. However, several aspects of this unique modification - the requirement for prior lysyl hydroxylation as a substrate, involvement of at least two distinct glycosyl transferases, its involvement in intermolecular crosslinking - have made its molecular mapping and quantitative characterization challenging. Such characterization is obviously crucial for understanding its biological significance. Recent progress in mass spectrometry has provided an unprecedented opportunity for this type of analysis. This review summarizes recent advances in the area of O-glycosylation of fibrillar collagens and their characterization using state-of-the-art liquid chromatography-mass spectrometry-based methodologies, and perspectives on future research. The analytical characterization of collagen crosslinking and advanced glycation end-products are not addressed here.

Abstract
Deciphering the biological and clinical significance of the proteins is investigated by mass spectrometry in a relatively new field, named proteomics. Mass spectrometry is, however, also used in chemistry for many years. In this Research Front we try to show the potential use of mass spectrometry in chemical, environmental and biomedical research and also to illustrate the applications of mass spectrometry in proteomics.
