ENZYME entry: EC 1.1.1.304

Accepted Name
diacetyl reductase [(S)-acetoin forming]
Alternative Name(s)
(S)-acetoin dehydrogenase
Reaction catalysed
(S)-acetoin + NAD(+) <=> diacetyl + H(+) + 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 bacteria Geobacillus stearothermophilus, Enterobacter aerogenes and Klebsiella pneumoniae.
  • Different from EC 1.1.1.303.
  • Formerly EC 1.1.1.5.
