ID 1.14.14.47 DE nitric-oxide synthase (flavodoxin). AN nitric oxide synthetase. AN NO synthase. CA 2 L-arginine + 4 O2 + 3 reduced [flavodoxin] = 5 H(+) + 4 H2O + CA 2 L-citrulline + 2 nitric oxide + 3 oxidized [flavodoxin]. CC -!- The enzyme, found in bacteria and archaea, consist of only an CC oxygenase domain and functions together with bacterial ferredoxins or CC flavodoxins. CC -!- The orthologous enzymes from plants and animals also contain a CC reductase domain and use only NADPH as the electron donor (cf. CC EC 1.14.13.39). CC -!- Formerly EC 1.14.13.165.
