oxoglutarate dehydrogenase (succinyl-transferring) activity
oxoglutarate dehydrogenase (succinyl-transferring) activity
Catalysis of the reaction: N(6)-[(R)-lipoyl]-L-lysyl-[dihydrolipoyllysine-residue succinyltransferase] + 2-oxoglutarate + H+ = N(6)-[(R)-S(8)-succinyldihydrolipoyl]-L-lysyl-[dihydrolipoyllysine-residue succinyltransferase] + CO2.
