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=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       Name=thiamine diphosphate; Xref=ChEBI:CHEBI:58937;

CC   -!- SUBUNIT: Heterodimer of an alpha and a beta chain.
