Protein
Dihydrolipoyllysine-residue acetyltransferase component of pyruvate dehydrogenase complex
Gene
aceF, sucB, Cgl2207, cg2421
Organism
Corynebacterium glutamicum (strain ATCC 13032 / DSM 20300 / JCM 1318 / LMG 3730 / NCIMB 10025)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

Is essential for both 2-oxoglutarate dehydrogenase (ODH) and pyruvate dehydrogenase (PDH) activities, but AceF has exclusively transacetylase (and no transsuccinylase) activity. The lipoyl residues required for ODH activity are likely provided by AceF.1 Publication

Catalytic activityi

Acetyl-CoA + enzyme N(6)-(dihydrolipoyl)lysine = CoA + enzyme N(6)-(S-acetyldihydrolipoyl)lysine.1 Publication

Cofactori

Binds 3 lipoyl cofactors covalently Inferred.1 Publication
