Comments
Comment typeDescription
Catalytic ActivitySuccinyl-CoA + enzyme N(6)- (dihydrolipoyl)lysine = CoA + enzyme N(6)-(S- succinyldihydrolipoyl)lysine.
CofactorName=(R)-lipoate; Xref=ChEBI:CHEBI:83088; Evidence={ECO:0000250}; Note=Binds 1 lipoyl cofactor covalently. {ECO:0000250};
FunctionThe 2-oxoglutarate dehydrogenase complex catalyzes the overall conversion of 2-oxoglutarate to succinyl-CoA and CO(2). It contains multiple copies of three enzymatic components: 2- oxoglutarate dehydrogenase (E1), dihydrolipoamide succinyltransferase (E2) and lipoamide dehydrogenase (E3) (By similarity). {ECO:0000250}.
PathwayAmino-acid degradation; L-lysine degradation via saccharopine pathway; glutaryl-CoA from L-lysine: step 6/6.
SimilarityBelongs to the 2-oxoacid dehydrogenase family. {ECO:0000305}.
SimilarityContains 1 lipoyl-binding domain. {ECO:0000255|PROSITE-ProRule:PRU01066, ECO:0000305}.
Subcellular LocationMitochondrion {ECO:0000269|PubMed:14671022}.
SubunitForms a 24-polypeptide structural core with octahedral symmetry. {ECO:0000250}.
