Comments [?]

Function E1 component of the 2-oxoglutarate dehydrogenase (OGDH) complex which catalyzes the decarboxylation of 2-oxoglutarate, the first step in the conversion of 2-oxoglutarate to succinyl-CoA and CO(2).
Catalytic activity RHEA:12188: 2-oxoglutarate + [dihydrolipoyllysine-residue succinyltransferase]-(R)-N(6)-lipoyl-L-lysine + H(+) = [dihydrolipoyllysine-residue succinyltransferase]-(R)-N(6)-(S(8)-succinyldihydrolipoyl)-L-lysine + CO2
EC 1.2.4.2
Cofactor thiamine diphosphate
Subunit Homodimer. Part of the 2-oxoglutarate dehydrogenase (OGDH) complex composed of E1 (2-oxoglutarate dehydrogenase), E2 (dihydrolipoamide succinyltransferase) and E3 (dihydrolipoamide dehydrogenase); the complex contains multiple copies of the three enzymatic components (E1, E2 and E3).
Similarity Belongs to the alpha-ketoglutarate dehydrogenase family.
