In enzymology a nitrite reductase (NO-forming) (EC 1.7.2.1) is an enzyme that catalyzes the chemical reactionnitric oxide + H2O + ferricytochrome c ⇌ nitrite + ferrocytochrome c + 2 H+The 3 substrates of this enzyme are nitric oxide H2O and ferricytochrome c whereas its 3 products are nitrite ferrocytochrome c and H+.This enzyme belongs to the family of oxidoreductases specifically those acting on other nitrogenous compounds as donors with a cytochrome as acceptor.
