Nitric oxide synthases (EC 1.14.13.39) (NOSs) are a family of enzymes catalyzing the production of nitric oxide (NO) from L-arginine. NO is an important cellular signaling molecule. It helps modulate vascular tone , insulin secretion, airway tone, and peristalsis , and is involved in angiogenesis and neural development.
Endothelial NOS (eNOS), also known as nitric oxide synthase 3 (NOS3) or constitutive NOS (cNOS), is an enzyme that in humans is encoded by the NOS3 gene located in the 7q35-7q36 region of chromosome 7. [5]
Nitric oxide synthases (EC 1.14.13.39) (NOSs) are a family of synthases that catalyze the production of nitric oxide (NO) from L-arginine.NO is a chemical messenger with diverse functions throughout the body depending on its enzymatic source and tissue localization.
Biological functions of nitric oxide are roles that nitric oxide plays within biology. Nitric oxide (nitrogen monoxide) is a molecule and chemical compound with chemical formula of N O . In mammals including humans, nitric oxide is a signaling molecule involved in several physiological and pathological processes. [ 1 ]
Nitric-oxide synthase (NAD(P)H-dependent) (EC 1.14.14.47, nitric oxide synthetase, NO synthase) is an enzyme with systematic name L-arginine,NAD(P)H:oxygen oxidoreductase (nitric-oxide-forming). [ 1 ] [ 2 ] [ 3 ] This enzyme catalyses the following chemical reaction

S-Nitrosylation similarly contributes to physiology and dysfunction of cardiac, airway and skeletal muscle and the immune system, reflecting wide-ranging functions in cells and tissues. [16] [17] [18] It is estimated that ~70% of the proteome is subject to S-nitrosylation and the majority of those sites are conserved. [19]
The endothelium maintains vascular homeostasis through the release of active vasodilators.Although nitric oxide (NO) is recognized as the primary factor at level of arteries, increased evidence for the role of another endothelium-derived vasodilator known as endothelium-derived hyperpolarizing factor (EDHF) has accumulated in the last years.
