ID   2.3.1.190
DE   acetoin dehydrogenase system.
AN   acetoin dehydrogenase.
CA   acetoin + CoA + NAD(+) = acetaldehyde + acetyl-CoA + H(+) + NADH.
CC   -!- Requires thiamine diphosphate.
CC   -!- It belongs to the 2-oxoacid dehydrogenase system family, which also
CC       includes EC 1.2.1.104, EC 1.2.1.105, EC 1.2.1.25 and EC 1.4.1.27.
CC   -!- With the exception of the glycine cleavage system, which contains 4
CC       components, the 2-oxoacid dehydrogenase systems share a common
CC       structure, consisting of three main components, namely a 2-oxoacid
CC       dehydrogenase (E1), a dihydrolipoamide acyltransferase (E2),
CC       and dihydrolipoamide dehydrogenase (E3).
