Oxoglutarate dehydrogenase

Description

Oxoglutarate dehydrogenase (ฮฑ-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 ยตM) but inactivated by high Ca2+ (>100 ยตM). OgDH is an important source of ROS.

Abbreviation: OgDH

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