EC 1.7.2.5     
Accepted name: nitric oxide reductase (cytochrome c)
Reaction: nitrous oxide + 2 ferricytochrome c + H2O = 2 nitric oxide + 2 ferrocytochrome c + 2 H+
Systematic name: nitrous oxide:ferricytochrome-c oxidoreductase
Comments: The enzyme from Pseudomonas aeruginosa contains a dinuclear centre comprising a non-heme iron centre and heme b3, plus heme c, heme b and calcium; the acceptor is cytochrome c551
