Comments

FUNCTION: The pyruvate dehydrogenase complex catalyzes the overall conversion of pyruvate to acetyl-CoA and CO(2). It contains multiple copies of three enzymatic components: pyruvate dehydrogenase (E1), dihydrolipoamide acetyltransferase (E2) and lipoamide dehydrogenase (E3) (By similarity).
CATALYTIC ACTIVITY: Pyruvate + [dihydrolipoyllysine-residue acetyltransferase] lipoyllysine = [dihydrolipoyllysine-residue acetyltransferase] S-acetyldihydrolipoyllysine + CO₂.
COFACTOR: Thiamine pyrophosphate (By similarity).
SUBUNIT: Tetramer of 2 alpha and 2 beta subunits (By similarity).
INTERACTION:

Q9NGT3:mdf-2; NbExp=1; IntAct=EBI-326559, EBI-328699;
Q09620:sdz-38; NbExp=1; IntAct=EBI-326559, EBI-332504;
SUBCELLULAR LOCATION: Mitochondrion matrix (By similarity).
