Exp. Bot. 66:2691-2708(2015). CC -!- FUNCTION: The 2-oxoglutarate dehydrogenase complex catalyzes the CC overall conversion of 2-oxoglutarate to succinyl-CoA and CO(2). It CC contains multiple copies of three enzymatic components: 2-oxoglutarate CC dehydrogenase (E1), dihydrolipoamide succinyltransferase (E2) and CC lipoamide dehydrogenase (E3) (By similarity). {ECO:0000250}. 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 -!- 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. {ECO:0000250}. CC -!- SUBCELLULAR LOCATION: Mitochondrion {ECO:0000269|PubMed:14671022, CC ECO:0000305|PubMed:25732537}. CC -!- SIMILARITY: Belongs to the 2-oxoacid dehydrogenase family. CC {ECO:0000305}.
