Protein

Dihydrolipoyllysine-residue acetyltransferase component of pyruvate dehydrogenase complex

Gene

pdhC

Organism
Acholeplasma laidlawii
Status
Reviewed-Annotation score: 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).

Catalytic activityi

Acetyl-CoA + enzyme N6-(dihydrolipoyl)lysine = CoA + enzyme N6-(S-acetyldihydrolipoyl)lysine.

Cofactori

(R)-lipoateCuratedNote: Binds 2 lipoyl cofactors covalently.Curated
