This enzyme belongs to the family of
oxidoreductases, specifically those acting on other nitrogenous compounds as donors with a cytochrome as acceptor. The
systematic name of this enzyme class is nitric-oxide:ferricytochrome-c oxidoreductase. Other names in common use include cd-cytochrome nitrite reductase, [nitrite reductase (cytochrome)] [misleading, see comments.], cytochrome c-551:O2, NO2+ oxidoreductase, cytochrome cd, cytochrome cd1, hydroxylamine (acceptor) reductase, methyl viologen-nitrite reductase, nitrite reductase (cytochrome, and NO-forming). This enzyme participates in
nitrogen metabolism. It has 3
cofactors:
FAD,
Iron, and
Copper.
