Nitric oxide reductase (menaquinol)
Nitric oxide reductase (menaquinol) (EC 1.7.5.2) is an enzyme.[1][2][3] This enzyme catalyses the following chemical reaction
- 2 nitric oxide + menaquinol nitrous oxide + menaquinone + H2O

Nitric oxide reductase contains copper.
In 2015 the laboratory that had characterized the Bacillus azotoformans enzyme wrote, "The copper-A-dependent Nor from Bacillus azotoformans uses cytochrome c₅₅₁ as electron donor but lacks menaquinol activity, in contrast to our earlier report."[4]
