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=(R)-N(6)-dihydrolipoyl-L-lysyl-[2-oxoglutarate dehydrogenase
CC complex component E2] + succinyl-CoA = (R)-N(6)-(S(8)-
CC succinyldihydrolipoyl)-L-lysyl-[2-oxoglutarate dehydrogenase complex
CC component E2] + CoA; Xref=Rhea:RHEA:15213, Rhea:RHEA-COMP:10581,
CC Rhea:RHEA-COMP:10582, ChEBI:CHEBI:57287, ChEBI:CHEBI:57292,
CC ChEBI:CHEBI:83100, 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 -!- SIMILARITY: Belongs to the 2-oxoacid dehydrogenase family.
CC {ECO:0000305}.
