ENZYME entry: EC 2.3.1.190

Accepted Name
Acetoin dehydrogenase.
Reaction catalysed
Acetoin + CoA + NAD(+) <=> acetaldehyde + acetyl-CoA + NADH
Cofactor(s)
Thiamine phosphate.
Comment(s)
  • This enzyme, which belongs to the family of 2-oxo acid dehydrogenase complexes, catalyzes the oxidative-hydrolytic cleavage of acetoin to acetaldehyde and acetyl-CoA in many bacterial strains, both aerobic and anaerobic.
  • The enzyme is composed of multiple copies of three enzymatic components:acetoin oxidoreductase (E1), dihydrolipoamide acetyltransferase (E2) and dihydrolipoyl dehydrogenase (E3).
