Protein name |
RecName:
|
Full=Nitrous-oxide reductase;
|
|
EC 1.7.2.4;
|
AltName:
|
Full=N(2)OR;
|
AltName:
|
Full=N2O reductase;
|
Flags:
|
Precursor;
|
|
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 |
RHEA:43108: 2 [Fe(III)cytochrome c] + H2O + N2 = 2 [Fe(II)cytochrome c] + 2 H(+) + nitrous oxide
EC 1.7.2.4
|
Cofactor |
Ca(2+) Note: Binds 2 calcium ions per subunit. |
|
Cu cation 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. |
Subunit |
Homodimer. |
Subcellular location |
Periplasm. |
case <Feature:PS51318>
Ptm |
Predicted to be exported by the Tat system. The position of the signal peptide cleavage has not been experimentally proven. |
end case
Similarity |
Belongs to the NosZ family. |
|
In the C-terminal section; belongs to the cytochrome c oxidase subunit 2 family. |
