General annotation (Comments)

Function

Nitrous-oxide reductase is part of a bacterial respiratory system which is activated under anaerobic conditions in the presence of nitrate or nitrous oxide By similarity. HAMAP MF_00716

Catalytic activity

N2 + H2O + acceptor = N2O + reduced acceptor. HAMAP MF_00716

Cofactor

Binds 2 calcium ions per subunit By similarity. HAMAP MF_00716

Binds 6 copper ions per subunit. Each subunit contains 2 copper centers; Cu(A) (binuclear) and Cu(Z) (tetranuclear). Cu(Z) is thought to be the site of nitrous oxide reduction By similarity. HAMAP MF_00716

Pathway

Nitrogen metabolism; nitrate reduction (denitrification); dinitrogen from nitrate: step 4/4. HAMAP MF_00716

Subunit structure

Homodimer By similarity. HAMAP MF_00716

Subcellular location

Periplasm By similarity HAMAP MF_00716.

Post-translational modification

Predicted to be exported by the Tat system. The position of the signal peptide cleavage has not been experimentally proven. HAMAP MF_00716

Sequence similarities

Belongs to the nosZ family.

In the C-terminal section; belongs to the cytochrome c oxidase subunit 2 family.
