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         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.
