Ferredoxin-nitrate reductase
- Ferredoxin-nitrate reductase
In enzymology, a ferredoxin---nitrate reductase (EC number|1.7.7.2) is an enzyme that catalyzes the chemical reaction
:nitrite + H2O + 2 oxidized ferredoxin nitrate + 2 reduced ferredoxin + 2 H+
The 3 substrates of this enzyme are nitrite, H2O, and oxidized ferredoxin, whereas its 3 products are nitrate, reduced ferredoxin, and H+.
This enzyme belongs to the family of oxidoreductases, specifically those acting on other nitrogenous compounds as donors with an iron-sulfur protein as acceptor. The systematic name of this enzyme class is nitrite:ferredoxin oxidoreductase. Other names in common use include assimilatory nitrate reductase, nitrate (ferredoxin) reductase, and assimilatory ferredoxin-nitrate reductase. This enzyme participates in nitrogen metabolism. It has 4 cofactors: iron, Sulfur, Molybdenum, and Iron-sulfur.
tructural studies
