Superfamily: Multifunctional 2-oxoglutarate metabolism enzyme, C-terminal domain

The 2-oxoglutarate dehydrogenase (OGDH) multienzyme complex is rate-limiting in the TCA cycle in many species, and is an essential nexus in the utilization of sugar and amino acids, funnelled via 2-oxoglutarate and oxidized to succinyl-CoA, process which releases CO2 and results in the reduction of NAD+ to NADH PMID:17367808.

An alternative name for this complex is alpha-ketoglutarate dehydrogenase (KGD). Structural domains comprising this superfamily are found at the C-terminus of the multifunctional 2-oxoglutarate metabolism enzyme KGD PMID:21867916.
