| - | [[Category: | + | [https://www.uniprot.org/uniprot/YAJL_ECOLI YAJL_ECOLI] Protein deglycase that repairs methylglyoxal- and glyoxal-glycated amino acids and proteins, and releases repaired proteins and lactate or glycolate, respectively. Deglycates cysteines, arginines and lysines residues in proteins, and thus reactivates these proteins by reversing glycation by glyoxals. Acts on early glycation intermediates (hemithioacetals and aminocarbinols), preventing the formation of advanced glycation endproducts (AGE) (PubMed:25416785) (By similarity). Displays a covalent chaperone activity with sulfenylated thiol proteins by forming mixed disulfides with members of the thiol proteome, and preferentially with sulfenylated cellular proteins, upon oxidative stress; these mixed disulfides can be subsequently reduced by low-molecular-weight thiols to regenerate YajL and reduced proteins (PubMed:22157000, PubMed:22321799). Involved in biogenesis of ribosomal proteins, probably as a ribosomal protein-folding chaperone. Confers resistance to oxidative stress. The chaperone activity reported for YajL is probably recruited to execute its deglycase activity, to interact with non-native glycated proteins and gain access to partially buried glycated sites.[UniProtKB:Q99497]<ref>PMID:20124404</ref> <ref>PMID:20889753</ref> <ref>PMID:22157000</ref> <ref>PMID:22321799</ref> <ref>PMID:25416785</ref> |
