Protein

Dihydrolipoyllysine-residue acetyltransferase component of pyruvate dehydrogenase complex

Gene

pdhC

Organism
Rickettsia typhi (strain ATCC VR-144 / Wilmington)
Status
Reviewed-Annotation score: -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).By similarity

Catalytic activityi

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

Cofactori

(R)-lipoateBy similarityNote: Binds 1 lipoyl cofactor covalently.By similarity
