Copper-containing nitrite reductase (CuNiR, EC 188.8.131.52, formerly EC 184.108.40.206) is an enzyme that catalyzes the one-electron reduction of nitrite (NO2 ) to nitric oxide (NO) and water. This enzyme is found in the periplasm of some bacteria, as well as in fungus, and is involved in the dissimilatory pathway of nitrogen metabolism. This enzyme contains multiple copper centers and should not be confused with other nitrite reductases, in particular the heme-containing cytochrome cd1 that is also found in denitrifiers (and with which shares the same ENZYME entry).
