CC   -!- FUNCTION: E1 component of the 2-oxoglutarate dehydrogenase (OGDH)
CC       complex which catalyzes the decarboxylation of 2-oxoglutarate, the
CC       first step in the conversion of 2-oxoglutarate to succinyl-CoA and
CC       CO(2). {ECO:0000255|HAMAP-Rule:MF_01169}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=(R)-N(6)-lipoyl-L-lysyl-[dihydrolipoyllysine-residue
CC         succinyltransferase] + 2-oxoglutarate + H(+) = (R)-N(6)-(S(8)-
CC         succinyldihydrolipoyl)-L-lysyl-[dihydrolipoyllysine-residue
CC         succinyltransferase] + CO2; Xref=Rhea:RHEA:12188, Rhea:RHEA-

CC         ChEBI:CHEBI:16526, ChEBI:CHEBI:16810, ChEBI:CHEBI:83099,

CC         Rule:MF_01169};
CC   -!- COFACTOR:
CC       Name=thiamine diphosphate; Xref=ChEBI:CHEBI:58937;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01169};
CC   -!- SUBUNIT: Homodimer. Part of the 2-oxoglutarate dehydrogenase (OGDH)
CC       complex composed of E1 (2-oxoglutarate dehydrogenase), E2
CC       (dihydrolipoamide succinyltransferase) and E3 (dihydrolipoamide
CC       dehydrogenase); the complex contains multiple copies of the three
CC       enzymatic components (E1, E2 and E3). {ECO:0000255|HAMAP-
CC       Rule:MF_01169}.
CC   -!- SIMILARITY: Belongs to the alpha-ketoglutarate dehydrogenase family.
CC       {ECO:0000255|HAMAP-Rule:MF_01169}.
