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=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 -!- 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}.
