CC -!- FUNCTION: The pyruvate dehydrogenase complex catalyzes the overall
CC conversion of pyruvate to acetyl-CoA and CO(2), and thereby links the
CC glycolytic pathway to the tricarboxylic cycle.
CC {ECO:0000256|ARBA:ARBA00003754}.
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,
