Nitric oxide dioxygenase (EC 1.14.12.17) is an enzyme that catalyzes the conversion of nitric oxide (NO) to nitrate (NO−3). The net reaction for the reaction catalyzed by nitric oxide dioxygenase is shown below: 2NO + 2O2 + NAD(P)H → 2NO3- + NAD(P)+ + H+Nitric oxide is a ubiquitous small molecule that is integrated in a wide variety of physiological processes including smooth muscle vasodilation platelet disaggregation neurotransmission and immune response to bacterial infection.
