General annotation (Comments)

Function

Plays a role in nitrite reduction By similarity.

Catalytic activity

NH3 + 2 H2O + 6 ferricytochrome c = nitrite + 6 ferrocytochrome c + 7 H+. HAMAP MF_01182

Cofactor

Binds 1 calcium ion per monomer By similarity.

Binds 5 heme groups covalently per monomer By similarity.

Pathway

Nitrogen metabolism; nitrate reduction (assimilation). HAMAP MF_01182

Subcellular location

Periplasm By similarity.

Miscellaneous

This protein is not predicted to have a signal sequence by the program SignalP. All others members of this family are periplasmic proteins. HAMAP MF_01182

Sequence similarities

Belongs to the cytochrome c-552 family.
