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) By similarity.

Catalytic activity

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

Cofactor

Thiamine pyrophosphate.

Subunit structure

Heterodimer of an alpha and a beta chain By similarity.

Subcellular location

Plastidchloroplast.
