CC -!- FUNCTION: The branched-chain alpha-keto dehydrogenase complex catalyzes
CC the overall conversion of alpha-keto acids to acyl-CoA and CO(2). It
CC contains multiple copies of three enzymatic components: branched-chain
CC alpha-keto acid decarboxylase (E1), lipoamide acyltransferase (E2) and
CC lipoamide dehydrogenase (E3).
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(R)-N(6)-lipoyl-L-lysyl-[dihydrolipoyllysine-residue (2-
CC methylpropanoyl)transferase] + 3-methyl-2-oxobutanoate + H(+) = (R)-
CC N(6)-(S(8)-2-methylpropanoyldihydrolipoyl)-L-lysyl-
CC [dihydrolipoyllysine-residue (2-methylpropanoyl)transferase] + CO2;

CC ChEBI:CHEBI:83099, ChEBI:CHEBI:83142; EC=1.2.4.4;
CC -!- COFACTOR:
CC Name=thiamine diphosphate; Xref=ChEBI:CHEBI:58937;
CC Evidence={ECO:0000250};
CC -!- SUBUNIT: Heterotetramer of alpha and beta chains. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion matrix {ECO:0000250}.
CC -!- MISCELLANEOUS: Bound potassium ions stabilize the protein structure.
CC {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the BCKDHA family. {ECO:0000305}.
