FunFam 7: Nitric oxide synthase oxygenase

There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Nitric-oxide synthase (flavodoxin). [EC: 1.14.14.47]
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.
