Biochemical and Structural Insights into the Winged Helix Domain of P150, the Largest Subunit of the Chromatin Assembly Factor 1. Int J Mol Sci 2022; 23:ijms23042160. [PMID: 35216276 PMCID: PMC8874411 DOI: 10.3390/ijms23042160] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2022] [Revised: 02/11/2022] [Accepted: 02/12/2022] [Indexed: 02/05/2023] Open
Abstract
The Chromatin Assembly Factor 1 is a heterotrimeric complex responsible for the nucleosome assembly during DNA replication and DNA repair. In humans, the largest subunit P150 is the major actor of this process. It has been recently considered as a tumor-associated protein due to its overexpression in many malignancies. Structural and functional studies targeting P150 are still limited and only scarce information about this subunit is currently available. Literature data and bioinformatics analysis assisted the identification of a stable DNA binding domain, encompassing residues from 721 to 860 of P150 within the full-length protein. This domain was recombinantly produced and in vitro investigated. An acidic region modulating its DNA binding ability was also identified and characterized. Results showed similarities and differences between the P150 and its yeast homologue, namely Cac-1, suggesting that, although sharing a common biological function, the two proteins may also possess different features.

Abstract
Beitang shrimp paste (BSP) is fermented by different parts of shrimp, such as the head (H), meat (M), or the whole shrimp (S and W). Microbial communities of BSP were dominated by Firmicutes and Proteobacteria at the phyla level and Tetragenococcus at the genus level. However, the microbial diversity of M was the lowest than the others. Non-dominant bacterial communities were presented by a mutual symbiotic model in BSP fermentation. Tetragenococcus, Halanaerobium, Streptococcus, and Brevundimonas were positively correlated with the biosynthesis of amino acids, fatty acids, and metabolic cofactors; Marinilactibacillus and Pseudomonas might be the main contributors to inorganic sulfides, nitrogen oxides, and long-chain alkanes in BSP; Psychrobacter was closely related to the ester characteristics of methyl palmitoleate and methyl hexadecanoate in H. Halanaerobium and Streptococcus promoted the production of pyrazines in S. Tetragenococcus was positively correlated with acetic acid, decanoic acid, and palmitic acid that improved the sour aroma of M. The relationship between bacteria and aroma formation under different raw materials was expected to improve the quality of BSP.

Abstract
Human carbonic anhydrase IX (hCA IX) is a tumour-associated enzyme present in a limited number of normal tissues, but overexpressed in several malignant human tumours. It is a transmembrane protein, where the extracellular region consists of a greatly investigated catalytic CA domain and a much less investigated proteoglycan-like (PG) domain. Considering its important role in tumour biology, here, we report for the first time the full characterization of the PG domain, providing insights into its structural and functional features. In particular, this domain has been produced at high yields in bacterial cells and characterized by means of biochemical, biophysical and molecular dynamics studies. Results show that it belongs to the family of intrinsically disordered proteins, being globally unfolded with only some local residual polyproline II secondary structure. The observed conformational flexibility may have several important roles in tumour progression, facilitating interactions of hCA IX with partner proteins assisting tumour spreading and progression.

Pawar AD, Verma D, Sankeshi V, Raman R, Sharma Y. Strategizing for the purification of a multiple Big domain-containing protein in native conformation is worth it! Protein Expr Purif 2017; 145:25-31.

Abstract
The reliability and accuracy of conformational or functional studies of any novel multidomain protein rely on the quality of protein. The bottleneck in structural studies with the complete Big_2 domain containing proteins like LigA, LigB or MpIBP is usually their large molecular size owing to their multidomain (>10-12 domains) architectures. Interestingly, a soil bacterium Paenarthrobacter aurescens TC1, harbours a gene that encodes a protein comprising of four predicted Big_2 domains. We report here the expression and purification of this novel, multiple Big_2 domains containing protein, Arig of P. aurescens TC1. During overexpression, recombinant Arig formed inclusion bodies and hence was purified by on-column refolding. The refolded Arig revealed a β-sheet conformation and a well-resolved near-UV CD spectra but did not exhibit a well-dispersed 2D [1H-15N]-HSQC NMR spectrum, as expected for a well-folded β-sheet native conformation. We, therefore, further optimized Arig overexpression in the soluble fraction by including osmolytes. CD spectroscopic and 2D [1H-15N]-HSQC analyses consolidate that Arig purified alternatively has a well-folded native conformation. While we describe different strategies for purification of Arig, we also present the spectral properties of this novel all-β-sheet protein.

Abstract
Prosystemin, originally isolated from Lycopersicon esculentum, is a tomato pro-hormone of 200 aminoacid residues which releases a bioactive peptide of 18 aminoacids called Systemin. This signaling peptide is involved in the activation of defense genes in solanaceous plants in response to herbivore feeding damage. Using biochemical, biophysical and bioinformatics approaches we characterized Prosystemin, showing that it is an intrinsically disordered protein possessing a few secondary structure elements within the sequence. Plant treatment with recombinant Prosystemin promotes early and late plant defense genes, which limit the development and survival of Spodoptera littoralis larvae fed with treated plants.

Abstract
Psychrobacter sp. DAB_AL43B, isolated from ornithogenic soil collected on the Arctic island of Spitsbergen, is a newly sequenced psychrophilic strain susceptible to conjugation and electrotransformation. Its genome consists of a circular chromosome (3.3 Mb) and four plasmids (4.4-6.4kb). In silico genome mining and microarray-based phenotypic analysis were performed to describe the metabolic potential of this strain and identify possible biotechnological applications. Metabolic reconstruction indicated that DAB_AL43B prefers low-molecular-weight carboxylates and amino acids as carbon and energy sources. Genetic determinants of heavy-metal resistance, anthracene degradation and possible aerobic denitrification were also identified. Comparative analyses revealed a relatively close relationship between DAB_AL43B and other sequenced Psychrobacter species. In addition, the plasmids of this strain were used as the basis for the construction of Escherichia coli-Psychrobacter spp. shuttle vectors. Taken together, the results of this work suggest that DAB_AL43B is a promising candidate as a new model strain for studies on Psychrobacter spp.

Abstract
Two thermostable α-carbonic anhydrases (α-CAs) isolated from thermophilic Sulfurihydrogenibium spp., namely SspCA (from S. yellowstonensis) and SazCA (from S. azorense), were shown in a previous work to possess interesting complementary properties. SspCA was shown to have an exceptional thermal stability, whereas SazCA demonstrated to be the most active α-CA known to date for the CO2 hydration reaction. Here we report the crystallographic structure of SazCA and the identification of the structural features responsible for its high catalytic activity, by comparing it with SspCA structure. These data are of relevance for the design of engineered proteins showing higher stability and catalytic activity than other α-CAs known to date.

Abstract
C3 and C4 plant carbonic anhydrases (CAs) are zinc-enzymes that catalyze the reversible hydration of CO2. They are sub-divided in three classes: α, β and γ, being distributed between both photosynthetic subtypes. The C4 dicotyledon species Flaveria bidentis (L.) "Kuntze" contains a small gene family encoding three distinct β-CAs, named FbiCA1, FbiCA2 and FbiCA3. We have expressed and purified recombinant FbiCA1, which is localized in the chloroplast where it is thought to play a role in lipid biosynthesis and antioxidant activity, and biochemically characterized it by spectroscopic and inhibition experiments. FbiCA1 is a compact octameric protein that is moderately inhibited by carboxylate molecules. Surprisingly, pyruvate, but not lactate, did not inhibit FbiCA1 at concentrations up to 10 mM, suggesting that its capacity to tolerate high pyruvate concentration reflects the high concentration of pyruvate in the chloroplasts of bundle-sheath and mesophyll cells involved in C4 photosynthesis.
