Function

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.

Caution

The sequence shown here is derived from an EMBL/GenBank/DDBJ whole genome shotgun (WGS) entry which is preliminary data.

Catalytic activity

Cofactor

Protein has several cofactor binding sites:
Ca2+ (UniProtKB | Rhea| CHEBI:29108 )

Note: Binds 2 calcium ions per subunit.
Cu cation (UniProtKB | Rhea| CHEBI:23378 )

Note: Binds 6 Cu cations 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.

Pathway

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