General annotation (Comments)

Function	The 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).
Catalytic activity	3-methyl-2-oxobutanoate + [dihydrolipoyllysine-residue (2-methylpropanoyl)transferase] lipoyllysine = [dihydrolipoyllysine-residue (2-methylpropanoyl)transferase] S-(2-methylpropanoyl)dihydrolipoyllysine + CO(2).
Cofactor	Thiamine pyrophosphate By similarity.
Subunit structure	Heterotetramer of alpha and beta chains By similarity.
Subcellular location	Mitochondrion matrixBy similarity.
Miscellaneous	Bound potassium ions stabilize the protein structure By similarity.
Sequence similarities	Belongs to the BCKDHA family.
