D-histidine 2-aminobutanoyltransferase

UniProtKB accession:  A0A0H3JXA8

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Catalyzes the nucleophilic attack of one alpha-aminobutanoate moiety from SAM onto D-histidine to produce the intermediate (2S)-2-amino-4-{[(1R)-1-carboxy-2-(1H-imidazol-4-yl)ethyl]amino}butanoate. Functions in the biosynthesis of the metallophore staphylopine, which is involved in the acquisition of nickel, cobalt, zinc, copper, and iron, and thus enables bacterial growth inside the host, where metal access is limited. Therefore, this enzyme probably contributes to staphylococcal virulence (PubMed:27230378, PubMed:29091735). Appears to be specific for D-histidine as substrate (PubMed:29091735).
