Oxoglutarate dehydrogenase
Description
Oxoglutarate dehydrogenase (α-ketoglutarate dehydrogenase) is a highly regulated enzyme of the tricarboxylic acid cycle. It catalyses the conversion of oxoglutarate (alpha-ketoglutarate) to succinyl-CoA, reduces NAD+ to NADH and thus links to Complex I in the Electron transfer-pathway. OgDH is activated by low Ca2+ (<20 µM) but inactivated by high Ca2+ (>100 µM). OgDH is an important source of ROS.

- The oxoglutarate dehydrogenase complex consists of the oxoglutarate dehydrogenase, dihydrolipoyl succinyltransferase (DLST) and dihydrolipoyl dehydrogenase (DLD).
- The reaction catalyzed by OgDH is:
- Oxoglutarate (α-ketoglutarate) + NAD+ + CoA → Succinyl CoA + CO2 + NADH + H+
- The reaction catalyzed by OgDH is:
