Comment typeDescription
Alternative ProductsEvent=Alternative splicing; Named isoforms=2; Name=1; IsoId=Q6P3A8-1; Sequence=Displayed; Name=2; IsoId=Q6P3A8-2; Sequence=VSP_029841; Note=No experimental confirmation available.;
Catalytic Activity3-methyl-2-oxobutanoate + [dihydrolipoyllysine-residue (2-methylpropanoyl)transferase] lipoyllysine = [dihydrolipoyllysine-residue (2- methylpropanoyl)transferase] S-(2- methylpropanoyl)dihydrolipoyllysine + CO(2).
FunctionThe branched-chain alpha-keto dehydrogenase complex catalyzes the overall conversion of alpha-keto acids to acyl-CoA and CO(2). It contains multiple copies of three enzymatic components: branched-chain alpha-keto acid decarboxylase (E1), lipoamide acyltransferase (E2) and lipoamide dehydrogenase (E3).
Subcellular LocationMitochondrion matrix.
SubunitHeterotetramer of 2 alpha and 2 beta chains. {ECO:0000250}.
