CC -!- FUNCTION: The pyruvate dehydrogenase complex catalyzes the overall
CC conversion of pyruvate to acetyl-CoA and CO(2). It contains multiple
CC copies of three enzymatic components: pyruvate dehydrogenase (E1),
CC dihydrolipoamide acetyltransferase (E2) and lipoamide dehydrogenase
CC (E3). {ECO:0000256|ARBA:ARBA00025211, ECO:0000256|RuleBase:RU366007}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H(+) + N(6)-[(R)-lipoyl]-L-lysyl-[dihydrolipoyllysine-residue
CC acetyltransferase] + pyruvate = CO2 + N(6)-[(R)-S(8)-
CC acetyldihydrolipoyl]-L-lysyl-[dihydrolipoyllysine-residue
CC acetyltransferase]; Xref=Rhea:RHEA:19189, Rhea:RHEA-COMP:10480,

CC Evidence={ECO:0000256|RuleBase:RU366007};
CC -!- COFACTOR:
CC Name=thiamine diphosphate; Xref=ChEBI:CHEBI:58937;
CC Evidence={ECO:0000256|ARBA:ARBA00001964,
CC ECO:0000256|RuleBase:RU366007};
CC -!- SUBUNIT: Heterodimer of an alpha and a beta chain.
CC {ECO:0000256|ARBA:ARBA00011870, ECO:0000256|RuleBase:RU366007}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
