Nitrogenase (flavodoxin)

From Wikipedia, the free encyclopedia

In enzymology, a nitrogenase (flavodoxin) (EC 1.19.6.1) is an enzyme that catalyzes the chemical reaction

6 reduced flavodoxin + 6 H⁺ + N₂ + n ATP 6 oxidized flavodoxin + 2 NH₃ + n ADP + n phosphate

The 4 substrates of this enzyme are reduced flavodoxin, H⁺, N2, and ATP, whereas its 4 products are oxidized flavodoxin, NH₃, ADP, and phosphate.

This enzyme belongs to the family of oxidoreductases, specifically those acting on reduced flavodoxin as dono with dinitrogen as acceptor. The systematic name of this enzyme class is reduced flavodoxin:dinitrogen oxidoreductase (ATP-hydrolysing). This enzyme participates in nitrogen metabolism. It has 2 cofactors: molybdenum, and Iron-sulfur.
