Protein

Dihydrolipoyllysine-residue succinyltransferase component of 2-oxoglutarate dehydrogenase complex

Gene

sucB

Organism
Azotobacter vinelandii
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at protein leveli

Functioni

The 2-oxoglutarate dehydrogenase complex catalyzes the overall conversion of 2-oxoglutarate to succinyl-CoA and CO2. It contains multiple copies of 3 enzymatic components: 2-oxoglutarate dehydrogenase (E1), dihydrolipoamide succinyltransferase (E2) and lipoamide dehydrogenase (E3).

Catalytic activityi

Succinyl-CoA + enzyme N(6)-(dihydrolipoyl)lysine = CoA + enzyme N(6)-(S-succinyldihydrolipoyl)lysine.

Cofactori

(R)-lipoateNote: Binds 1 lipoyl cofactor covalently.
