Molecular classification
Enzyme, Oxidoreductase, Dehydrogenase complex
01

Overview

Alpha-ketoglutarate dehydrogenase complex (α-KGDH or KGDHC) is a large mitochondrial enzyme complex that catalyzes the oxidative decarboxylation of alpha-ketoglutarate to succinyl-CoA and CO₂ in the citric acid (Krebs) cycle. This reaction also produces NADH, which directly supplies electrons to the respiratory chain for ATP production. Impaired function of this enzyme has been found to be characteristic for several neurodegenerative diseases.
