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).
  • SUBCELLULAR LOCATION: Mitochondrion matrix.
