Reaction: (R)-mandelate + NAD+ = phenylglyoxylate + NADH + H+
Glossary: (R)-mandelate = D-mandelate
Other name(s): ManDH2; D-ManDH2; D-mandelate dehydrogenase (ambiguous)
Systematic name: (R)-mandelate:NAD+ 2-oxidoreductase
Comments: The enzyme, found in bacteria and fungi, can also accept a number of substituted mandelate derivatives, such as 3-hydroxymandelate, 4-hydroxymandelate, 2-methoxymandelate, 4-hydroxy-3-methoxymandelate and 3-hydroxy-4-methoxymandelate. The enzyme has no activity with (S)-mandelate (cf. EC 18.104.22.168, (S)-mandelate dehydrogenase) [1,2]. The enzyme transfers the pro-R-hydrogen from NADH .
