Glyceraldehyde-3-phosphate dehydrogenase (ferredoxin)

In enzymology, a glyceraldehyde-3-phosphate dehydrogenase (ferredoxin) (EC 1.2.7.6) is an enzyme that catalyzes the chemical reaction

D-glyceraldehyde-3-phosphate + H₂O + 2 oxidized ferredoxin ${\displaystyle \rightleftharpoons }$ 3-phospho-D-glycerate + 2 H⁺ + 2 reduced ferredoxin

The 3 substrates of this enzyme are D-glyceraldehyde-3-phosphate, H₂O, and oxidized ferredoxin, whereas its 3 products are 3-phospho-D-glycerate, H⁺, and reduced ferredoxin.

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 D-glyceraldehyde-3-phosphate:ferredoxin oxidoreductase. Other names in common use include GAPOR, glyceraldehyde-3-phosphate Fd oxidoreductase, and glyceraldehyde-3-phosphate ferredoxin reductase.
