IUBMB Comments
Requires thiamine diphosphate. This enzyme, which belongs to the family of 2-oxo acid dehydrogenase complexes, catalyses 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 enzymic components: acetoin oxidoreductase (E1), dihydrolipoamide acetyltransferase (E2) and dihydrolipoyl dehydrogenase (E3).
