General annotation (Comments)

Function

The pyruvate dehydrogenase complex catalyzes the overall conversion of pyruvate to acetyl-CoA and CO2. It contains multiple copies of three enzymatic components: pyruvate dehydrogenase (E1), dihydrolipoamide acetyltransferase (E2) and lipoamide dehydrogenase (E3).

Catalytic activity

Pyruvate + [dihydrolipoyllysine-residue acetyltransferase] lipoyllysine = [dihydrolipoyllysine-residue acetyltransferase] S-acetyldihydrolipoyllysine + CO2.

Cofactor

Thiamine pyrophosphate By similarity.

Enzyme regulation

E1 activity is regulated by phosphorylation (inactivation) and dephosphorylation (activation) of the alpha subunit By similarity.

Subunit structure

Tetramer of 2 alpha and 2 beta subunits By similarity.

Subcellular location

Mitochondrion matrix By similarity.
