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}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=acetyl-CoA + N(6)-[(R)-dihydrolipoyl]-L-lysyl-[protein] = CoA
CC + N(6)-[(R)-S(8)-acetyldihydrolipoyl]-L-lysyl-[protein];
CC Xref=Rhea:RHEA:17017, Rhea:RHEA-COMP:10475, Rhea:RHEA-COMP:10478,
CC ChEBI:CHEBI:57287, ChEBI:CHEBI:57288, ChEBI:CHEBI:83100,
CC ChEBI:CHEBI:83111; EC=2.3.1.12;
CC Evidence={ECO:0000256|ARBA:ARBA00043782,
CC ECO:0000256|RuleBase:RU361137};
CC -!- COFACTOR:
CC Name=(R)-lipoate; Xref=ChEBI:CHEBI:83088;
CC Evidence={ECO:0000256|RuleBase:RU361137};
CC Note=Binds 1 lipoyl cofactor covalently.
CC {ECO:0000256|RuleBase:RU361137};
CC -!- SUBUNIT: Forms a 24-polypeptide structural core with octahedral
CC symmetry. {ECO:0000256|ARBA:ARBA00011484}.
CC -!- SIMILARITY: Belongs to the 2-oxoacid dehydrogenase family.
CC {ECO:0000256|ARBA:ARBA00007317, ECO:0000256|RuleBase:RU361137}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
