EC 1.5.1.52     
Accepted name: staphylopine dehydrogenase
Reaction: staphylopine + NADP+ + H2O = (2S)-2-amino-4-{[(1R)-1-carboxy-2-(1H-imidazol-4-yl)ethyl]amino}butanoate + pyruvate + NADPH + H+
Glossary: staphylopine = (2S)-4-{[(1R)-1-carboxy-2-(1H-imidazol-4-yl)ethyl]amino}-2-[(1-carboxyethyl)amino]butanoate
Other name(s): cntM (gene name); staphylopine synthase
Systematic name: staphylopine:NADP+ oxidoreductase [(2S)-2-amino-4-{[(1R)-1-carboxy-2-(1H-imidazol-4-yl)ethyl]amino}butanoate]-forming
Comments: The enzyme, characterized from the bacterium Staphylococcus aureus, catalyses the last reaction in the biosynthesis of the metallophore staphylopine, which is involved in the acquisition of nickel, copper, and cobalt.
