Enzyme Information

1.7.2.5

Nitric-oxide reductase (cytochrome c).

based on mapping to UniProt Q59647

Nitrous oxide + 2 ferricytochrome c + H(2)O = 2 nitric oxide + 2 ferrocytochrome c + 2 H(+).

-!- The enzyme from Pseudomonas aeruginosa contains a dinuclear center comprising a non-heme iron center and heme b3, plus heme c, heme b and calcium; the acceptor is cytochrome c551. -!- Formerly EC 1.7.99.7.
