The first nitric oxide synthase to be identified was found in neuronal tissue (NOS1 or nNOS); the endothelial NOS (eNOS or NOS3) was the third to be identified. They were originally classified as "constitutively expressed" and "Ca 2+ sensitive" but it is now known that they are present in many different cell types and that expression is ...
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]
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 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.
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
EDRF is produced from L-arginine by an enzyme (endothelial nitric oxide synthase) that is dependent on calcium-calmodulin and NADPH - this occurs in the cardiac endothelium. [citation needed] EDRF then diffuses to the smooth muscle in vascular tissue (vessels may be large or small), here it enacts endogenous vasodilation. Moreover, it serves ...

RNS are produced in animals starting with the reaction of nitric oxide (•NO) with superoxide (O 2 •−) to form peroxynitrite (ONOO −): [4] [5] •NO (nitric oxide) + O 2 •− (superoxide) → ONOO − (peroxynitrite) Superoxide anion (O 2 −) is a reactive oxygen species that reacts quickly with nitric oxide (NO) in the vasculature ...
