nasD

Assimilatory ferredoxin-dependent nitrite reductase

586 amino acids

Catalyzes the reduction of nitrite to ammonium in the nitrate assimilation pathway, using ferredoxin as the electron donor. Can use reduced methyl viologen but neither NADPH nor NADH as electron donors.

Belongs to the nitrite and sulfite reductase 4Fe-4S domain family.

65.438 kDa
