Protein

Dihydrolipoyllysine-residue succinyltransferase component of 2-oxoglutarate dehydrogenase complex

Gene

odhB

Organism
Staphylococcus aureus (strain MRSA252)
Status
Reviewed-Annotation score: -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 N6-(dihydrolipoyl)lysine = CoA + enzyme N6-(S-succinyldihydrolipoyl)lysine.

Cofactori

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

Pathwayi: L-lysine degradation via saccharopine pathway

This protein is involved in step 6 of the subpathway that synthesizes glutaryl-CoA from L-lysine.
Proteins known to be involved in the 6 steps of the subpathway in this organism are:
  1. no protein annotated in this organism
  2. no protein annotated in this organism
  3. no protein annotated in this organism
  4. no protein annotated in this organism
  5. no protein annotated in this organism
  6. Dihydrolipoyllysine-residue succinyltransferase component of 2-oxoglutarate dehydrogenase complex (odhB)
This subpathway is part of the pathway L-lysine degradation via saccharopine pathway, which is itself part of Amino-acid degradation.
