Protein

Dihydrolipoyllysine-residue succinyltransferase component of 2-oxoglutarate dehydrogenase complex

Gene

sucB

Organism
Haemophilus influenzae (strain ATCC 51907 / DSM 11121 / KW20 / Rd)
Status
Reviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

Functioni

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

Catalytic activityi

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

Cofactori

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