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.

Catalytic activity

N(2) + H(2)O + acceptor = N(2)O + reduced acceptor.

Cofactor

Binds 2 calcium ions per subunit By similarity.

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.

Pathway

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

Subunit structure

Homodimer By similarity.

Subcellular location

Periplasm.

Post-translational modification

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

Sequence similarities

Belongs to the nosZ family.

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