CC -!- FUNCTION: Nitrous-oxide reductase is part of a bacterial respiratory
CC system which is activated under anaerobic conditions in the presence of
CC nitrate or nitrous oxide. {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2 Fe(III)-[cytochrome c] + H2O + N2 = 2 Fe(II)-[cytochrome c]
CC + 2 H(+) + nitrous oxide; Xref=Rhea:RHEA:43108, Rhea:RHEA-COMP:10350,
CC Rhea:RHEA-COMP:14399, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:17045, ChEBI:CHEBI:17997, ChEBI:CHEBI:29033,
CC ChEBI:CHEBI:29034; EC=1.7.2.4;
CC -!- COFACTOR:
CC Name=Ca(2+); Xref=ChEBI:CHEBI:29108; Evidence={ECO:0000250};
CC Note=Binds 2 calcium ions per subunit. {ECO:0000250};
CC -!- COFACTOR:
CC Name=Cu cation; Xref=ChEBI:CHEBI:23378; Evidence={ECO:0000250};
CC Note=Binds 6 Cu cations per subunit. Each subunit contains 2 copper
CC centers; Cu(A) (binuclear) and Cu(Z) (tetranuclear). Cu(Z) is thought
CC to be the site of nitrous oxide reduction. {ECO:0000250};
CC -!- PATHWAY: Nitrogen metabolism; nitrate reduction (denitrification);
CC dinitrogen from nitrate: step 4/4.
CC -!- SUBUNIT: Homodimer. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Periplasm {ECO:0000250}.
CC -!- PTM: Predicted to be exported by the Tat system. The position of the
CC signal peptide cleavage has not been experimentally proven.
CC -!- SIMILARITY: Belongs to the NosZ family. {ECO:0000305}.
CC -!- SIMILARITY: In the C-terminal section; belongs to the cytochrome c
CC oxidase subunit 2 family. {ECO:0000305}.
