General annotation (Comments)

Function	The 2-oxoglutarate dehydrogenase complex catalyzes the overall conversion of 2-oxoglutarate to succinyl-CoA and CO2. It contains multiple copies of three enzymatic components: 2-oxoglutarate dehydrogenase (E1), dihydrolipoamide succinyltransferase (E2) and lipoamide dehydrogenase (E3) By similarity.
Catalytic activity	2-oxoglutarate + [dihydrolipoyllysine-residue succinyltransferase] lipoyllysine = [dihydrolipoyllysine-residue succinyltransferase] S-succinyldihydrolipoyllysine + CO2.
Cofactor	Thiamine pyrophosphate By similarity.
Subcellular location	Mitochondrion Potential.
Sequence similarities	Belongs to the alpha-ketoglutarate dehydrogenase family.
Sequence caution	The sequence BAB13456.1 differs from that shown. Reason: Miscellaneous discrepancy. Chimeric cDNA. C-terminal exons are derived from the neighboring gene.
