Nitric oxide reductase (cytochrome c) (EC 1.7.2.5) is an enzyme with systematic name nitrous oxide:ferricytochrome-c oxidoreductase.[1][2][3][4][5][6] This enzyme catalyses the following chemical reaction

nitrous oxide + 2 ferricytochrome c + H2O 2 nitric oxide + 2 ferrocytochrome c + 2 H+

The enzyme from Pseudomonas aeruginosa contains a dinuclear centre.
