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) (By similarity). {ECO:0000250}.
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   -!- COFACTOR:
CC       Name=(R)-lipoate; Xref=ChEBI:CHEBI:83088; Evidence={ECO:0000250};
CC       Note=Binds 1 lipoyl cofactor covalently. {ECO:0000250};
CC   -!- SUBUNIT: Forms a 24-polypeptide structural core with octahedral
CC       symmetry. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the 2-oxoacid dehydrogenase family.
CC       {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=AAM67764.1; Type=Erroneous initiation; Evidence={ECO:0000305};
