Enzyme Information

1.2.4.1
Pyruvate dehydrogenase (acetyl-transferring).
based on mapping to UniProt P21874
Pyruvate + [dihydrolipoyllysine-residue acetyltransferase] lipoyllysine = [dihydrolipoyllysine-residue acetyltransferase] S-acetyldihydrolipoyllysine + CO(2).
-!- It is a component (in multiple copies) of the multienzyme pyruvate dehydrogenase complex in which it is bound to a core of molecules of EC 2.3.1.12, which also binds multiple copies of EC 1.8.1.4. -!- It does not act on free lipoamide or lipoyllysine, but only on the lipoyllysine residue in EC 2.3.1.12.
