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
