ENZYME entry: EC 1.1.1.303

Accepted Name
Diacetyl reductase ((R)-acetoin forming).
Alternative Name(s)
(R)-acetoin dehydrogenase.
Reaction catalysed
(R)-acetoin + NAD(+) <=> diacetyl + NADH
Comment(s)
  • The reaction is catalyzed in the reverse direction.
  • This activity is usually associated with butanediol dehydrogenase activity (EC 1.1.1.4 or EC 1.1.1.76).
  • While the butanediol dehydrogenase activity is reversible, diacetyl reductase activity is irreversible.
  • This enzyme has been reported in the yeast Saccharomyces cerevisiae.
  • Different from EC 1.1.1.304.
  • Formerly EC 1.1.1.5.
