Enzyme Information
| 1.14.14.47 |
Nitric-oxide synthase (flavodoxin).
based on mapping to UniProt O34453
2 L-arginine + 3 reduced flavodoxin + 4 O(2) = 2 L-citrulline + 2 nitric oxide + 3 oxidized flavodoxin + 4 H(2)O.
-!- The enzyme, found in bacteria and archaea, consist of only an oxygenase domain and functions together with bacterial ferredoxins or flavodoxins. -!- The orthologous enzymes from plants and animals also contain a reductase domain and use only NADPH as the electron donor (cf. EC 1.14.13.39). -!- Formerly EC 1.14.13.165.
