Description Histidine racemase
Catalyzed reaction L-histidine = D-histidine
Cofactor Pyridoxal phosphate or no cofactor
Comments The enzyme characterized from the bacterium Staphylococcus aureus is PLP-independent and participates in the biosynthesis of the metallophore staphylopine, which is involved in the acquisition of nickel, copper, and cobalt.
A peculiar PLP-dependent His racemase was found only in lactic acid bacteria of the genus Leuconostoc.
