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. HAMAP MF_00716
Catalytic activity	N₂ + H₂O + acceptor = N₂O + reduced acceptor. HAMAP MF_00716
Cofactor	Binds 2 calcium ions per subunit. HAMAP MF_00716 Binds 6 copper ions 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. 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 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 The N-terminus is blocked. HAMAP MF_00716
Sequence similarities	Belongs to the nosZ family. In the C-terminal section; belongs to the cytochrome c oxidase subunit 2 family.
