CC -!- FUNCTION: E2 component of the 2-oxoglutarate dehydrogenase (OGDH)
CC complex which catalyzes the second step in the conversion of 2-
CC oxoglutarate to succinyl-CoA and CO(2).
CC {ECO:0000256|ARBA:ARBA00004052}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=N(6)-[(R)-dihydrolipoyl]-L-lysyl-[2-oxoglutarate dehydrogenase
CC complex component E2] + succinyl-CoA = CoA + N(6)-[(R)-S(8)-
CC succinyldihydrolipoyl]-L-lysyl-[2-oxoglutarate dehydrogenase complex
CC component E2]; Xref=Rhea:RHEA:15213, Rhea:RHEA-COMP:10581, Rhea:RHEA-

CC Evidence={ECO:0000256|ARBA:ARBA00043693};
CC -!- COFACTOR:
CC Name=(R)-lipoate; Xref=ChEBI:CHEBI:83088;
CC Evidence={ECO:0000256|ARBA:ARBA00001938};
CC -!- PATHWAY: Amino-acid degradation; L-lysine degradation via saccharopine
CC pathway; glutaryl-CoA from L-lysine: step 6/6.
CC {ECO:0000256|ARBA:ARBA00005145}.
CC -!- SIMILARITY: Belongs to the 2-oxoacid dehydrogenase family.
CC {ECO:0000256|ARBA:ARBA00007317}.
