Protein

Pyruvate dehydrogenase E1 component subunit alpha

Gene
pdhA, BCE_G9241_3962
Organism
Bacillus cereus
Status
Reviewed - Annotation score: 3 out of 5 - Experimental evidence at protein leveli

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.By similarity

Catalytic activityi

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

Cofactori

Thiamine pyrophosphate By similarity.By similarity
