2-oxoglutarate synthase

In enzymology, 2-oxoglutarate synthase is an enzyme that catalyzes the chemical reaction
The substrates of this enzyme are succinyl-CoA, reduced ferredoxin, carbon dioxide and two protons. Its products are 2-oxoglutaric acid, coenzyme A, and oxidized ferredoxin. This reaction is part of the reverse Krebs cycle, as a means of carbon fixation.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the aldehyde or oxo group of donor with an iron-sulfur protein as acceptor. The systematic name of this enzyme class is 2-oxoglutarate:ferredoxin oxidoreductase . Other names in common use include 2-ketoglutarate ferredoxin oxidoreductase, 2-oxoglutarate:ferredoxin oxidoreductase, KGOR, 2-oxoglutarate ferredoxin oxidoreductase, and 2-oxoglutarate:ferredoxin 2-oxidoreductase . In the direction from 2-oxoglutaric acid to succinyl-CoA the enzyme is part of the citric acid cycle.
