FUNCTION: The 2-oxoglutarate dehydrogenase complex catalyzes the overall conversion of 2-oxoglutarate to succinyl-CoA and CO(2). It contains multiple copies of three enzymatic components: 2-oxoglutarate dehydrogenase (E1), dihydrolipoamide succinyltransferase (E2) and lipoamide dehydrogenase (E3) (By similarity).
CATALYTIC ACTIVITY: 2-oxoglutarate + [dihydrolipoyllysine-residue succinyltransferase] lipoyllysine = [dihydrolipoyllysine-residue succinyltransferase] S-succinyldihydrolipoyllysine + CO₂.
COFACTOR: Thiamine pyrophosphate (By similarity).
SUBUNIT: Homodimer (By similarity).
SIMILARITY: Belongs to the alpha-ketoglutarate dehydrogenase family.
