Although the early release of nitric oxide through the activity of constitutive nitric-oxide synthase is important in maintaining the dilation of blood vessels , the much higher concentrations of nitric oxide produced by inducible nitric-oxide synthase in macrophages can result in oxidative damage. Peroxynitrite (oxoperoxonitrate(-1)), anion of peroxynitrous acid, is thought to mediate the toxic action of nitric oxide and superoxide anion. Epub 2012 Apr 18. Epub 2008 Jan 24. A tryptophan that modulates tetrahydrobiopterin-dependent electron transfer in nitric oxide synthase regulates enzyme catalysis by additional mechanisms. 1998; 97:576–580. -> increase in cGMP –. It relaxes vascular smooth muscle by binding to the heme moiety of cytosolic guanylate cyclase, activating guanylate cyclase and increasing intracellular levels of cyclic guanosine 3',5'-monophosphate, which then leads to vasodilation. The synthesis of nitric oxide is catalyzed by enzyme nitric oxide synthase (NOS) which has three isoforms: endothelial nitric oxide synthase, neuronal nitric oxide synthase, macrophagal nitric oxide synthase. -> smooth muscle relaxation. J Leukoc Biol. Single electron makes it into very reactive radical, interacting with metals incorporated in enzyme structure, heme, superoxids, oxygen, etc. These features determine differences of activation pathways as well as specificity of inhibitors. Abstract —The precise mechanisms by which nitric oxide (NO) decreases free [Ca 2+] i, inhibits Ca 2+ influx, and relaxes vascular smooth muscle are poorly understood. One way or another, nitric oxide ends up as methaemoglobin and nitrate. The endothelial cell production of nitric oxide (NO) accounts for endothelium-dependent vasodilatation.
