General annotation (Comments)

Function

Inactivation of this cytochrome oxidase results in the loss of nitrite and nitric oxide reductase activities, but not of nitrous oxide reductase activity.

Catalytic activity

Nitric oxide + H2O + ferricytochrome c = nitrite + ferrocytochrome c + 2 H+.

NH3 + H2O + acceptor = hydroxylamine + reduced acceptor.

Cofactor

Binds 2 heme groups per subunit By similarity.

Subunit structure

Homodimer By similarity.

Subcellular location

Periplasm By similarity.

Sequence similarities

Contains 1 cytochrome c domain.
