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). {ECO:0000256|RuleBase:RU365014}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=3-methyl-2-oxobutanoate + H(+) + N(6)-[(R)-lipoyl]-L-lysyl-
CC [dihydrolipoyllysine-residue (2-methylpropanoyl)transferase] = CO2 +
CC N(6)-[(R)-S(8)-2-methylpropanoyldihydrolipoyl]-L-lysyl-
CC [dihydrolipoyllysine-residue (2-methylpropanoyl)transferase];
CC Xref=Rhea:RHEA:13457, Rhea:RHEA-COMP:10488, Rhea:RHEA-COMP:10489,
CC ChEBI:CHEBI:11851, ChEBI:CHEBI:15378, ChEBI:CHEBI:16526,
CC ChEBI:CHEBI:83099, ChEBI:CHEBI:83142; EC=1.2.4.4;
CC Evidence={ECO:0000256|RuleBase:RU365014};
CC -!- COFACTOR:
CC Name=thiamine diphosphate; Xref=ChEBI:CHEBI:58937;
CC Evidence={ECO:0000256|RuleBase:RU365014};
CC -!- SIMILARITY: Belongs to the BCKDHA family.
CC {ECO:0000256|RuleBase:RU365014}.
