Enzyme Information
| 1.7.2.4 |
Nitrous-oxide reductase.
based on mapping to UniProt P19573
Nitrogen + H(2)O + 2 ferricytochrome c = nitrous oxide + 2 ferrocytochrome c + 2 H(+).
-!- The reaction is observed only in the direction of nitrous oxide reduction. -!- Contains the mixed-valent dinuclear CuA species at the electron entry site of the enzyme, and the tetranuclear Cu-Z center in the active site. -!- In Paracoccus pantotrophus, the electron donor is cytochrome c552. -!- Formerly EC 1.7.99.6.
