IUBMB Enzyme Nomenclature


Accepted name: benzil reductase [(R)-benzoin forming]

Reaction: (R)-benzoin + NADP+ = benzil + NADPH + H+

Glossary: (R)-benzoin = (2R)-2-hydroxy-1,2-diphenylethanone
benzil = 1,2-diphenylethane-1,2-dione

Systematic name: (R)-benzoin:NADP+ oxidoreductase

Comments: The enzyme from the bacterium Xanthomonas oryzae is able to reduce enantioselectively only one of the two carbonyl groups of benzil to give optically active (R)-benzoin.
