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). {ECO:0000250|UniProtKB:P0AFG6}.
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         COMP:10582, ChEBI:CHEBI:57287, ChEBI:CHEBI:57292, ChEBI:CHEBI:83100,
CC         ChEBI:CHEBI:83120; EC=2.3.1.61;
CC         Evidence={ECO:0000250|UniProtKB:P0AFG6};
CC   -!- COFACTOR:
CC       Name=(R)-lipoate; Xref=ChEBI:CHEBI:83088; Evidence={ECO:0000250};
CC       Note=Binds 1 lipoyl cofactor covalently. {ECO:0000250};
CC   -!- PATHWAY: Amino-acid degradation; L-lysine degradation via saccharopine
CC       pathway; glutaryl-CoA from L-lysine: step 6/6.
CC   -!- SUBUNIT: Forms a 24-polypeptide structural core with octahedral
CC       symmetry. Part of the 2-oxoglutarate dehydrogenase (OGDH) complex
CC       composed of E1 (2-oxoglutarate dehydrogenase), E2 (dihydrolipoamide
CC       succinyltransferase) and E3 (dihydrolipoamide dehydrogenase); the
CC       complex contains multiple copies of the three enzymatic components (E1,
CC       E2 and E3). {ECO:0000250|UniProtKB:P0AFG6}.
CC   -!- INDUCTION: By 2,4-dichlorophenol. {ECO:0000269|PubMed:15073309}.
CC   -!- SIMILARITY: Belongs to the 2-oxoacid dehydrogenase family.
CC       {ECO:0000305}.
