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).
CC       {ECO:0000250|UniProtKB:Q02218}.
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         Evidence={ECO:0000250|UniProtKB:Q02218};
CC   -!- COFACTOR:
CC       Name=thiamine diphosphate; Xref=ChEBI:CHEBI:58937;
CC         Evidence={ECO:0000250|UniProtKB:Q02218};
CC   -!- SUBCELLULAR LOCATION: Mitochondrion matrix {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the alpha-ketoglutarate dehydrogenase family.
CC       {ECO:0000305}.
