General annotation (Comments)

Function	The branched-chain alpha-keto dehydrogenase complex catalyzes the overall conversion of alpha-keto acids to acyl-CoA and CO2. 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 + CO2.
Subunit structure	Heterodimer of an alpha and a beta chain.
Subcellular location	Mitochondrion matrix.
Sequence caution	The sequence AAA73899.1 differs from that shown. Reason: Frameshift at positions 101 and 120. The sequence AAA73899.1 differs from that shown. Reason: Miscellaneous discrepancy. Contaminating sequence. Sequence of unknown origin in the N-terminal part.
