Enzyme Information

1.7.2.4

Nitrous-oxide reductase.

based on mapping to UniProt Q51705

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.
