Staphylopine synthase

UniProtKB accession:  A0A0H3JT80

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Catalyzes the NADPH-dependent reductive condensation of pyruvate to the intermediate formed by the adjacently encoded enzyme CntL, namely (2S)-2-amino-4-{[(1R)-1-carboxy-2-(1H-imidazol-4-yl)ethyl]amino}butanoate, leading to the production of staphylopine. This is the last step 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. Can use neither NADH nor alpha-ketoglutarate in place of NADPH and pyruvate, respectively.
