Protein
Pyruvate dehydrogenase E1 component subunit beta
Gene
pdhB, odpB
Organism
Mesostigma viride (Green alga)
Status
Reviewed - Annotation score: 2 out of 5 - Protein inferred from homologyi

Functioni

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 activityi

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

Cofactori

Thiamine pyrophosphate.
