Term Name:	branched-chain alpha-keto acid dehydrogenase activity
Synonyms:	2-oxoisovalerate dehydrogenase (acylating) activity, 2-oxoisovalerate dehydrogenase activity, 3-methyl-2-oxobutanoate:NAD+ 2-oxidoreductase (CoA-methyl-propanoylating)
Definition:	Catalysis of the reaction: [a branched-chain alpha-keto acid] + CoA + NAD+ = [a branched-chain acyl-CoA] + CO2 + NADH. This enzyme system catalyzes the oxidative decarboxylation of branched-chain alpha-keto acids derived from L-leucine, L-isoleucine, and L-valine to branched-chain acyl-CoAs.
