branched-chain 2-oxo acid dehydrogenase activity dihydrolipoyl dehydrogenase (NADH) activity dihydrolipoamide branched chain acyltransferase activity obsolete branched-chain alpha-keto acid dehydrogenase activity https://github.com/geneontology/go-ontology/issues/26124 https://github.com/geneontology/go-ontology/issues/28526 true GO:0047101 OBSOLETE. 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. molecular_function This term was obsoleted because it represents multiple activities. branched-chain alpha-keto acid decarboxylation to branched-chain acyl-CoA
