ENZYME entry: EC 2.3.1.190

Accepted Name
Acetoin dehydrogenase system.
Alternative Name(s)
Acetoin dehydrogenase.
Reaction catalysed
Acetoin + CoA + NAD(+) <=> acetaldehyde + acetyl-CoA + NADH
Cofactor(s)
Thiamine phosphate.
Comment(s)
  • Requires thiamine diphosphate.
  • It belongs to the 2-oxoacid dehydrogenase system family, which also includes EC 1.2.1.104, EC 1.2.1.105, EC 1.2.1.25 and EC 1.4.1.27.
  • With the exception of the glycine cleavage system, which contains 4 components, the 2-oxoacid dehydrogenase systems share a common structure, consisting of three main components, namely a 2-oxoacid dehydrogenase (E1), a dihydrolipoamide acyltransferase (E2), and dihydrolipoamide dehydrogenase (E3).
