Biochem/physiol Actions

NOS is responsible for the biosynthesis of nitric oxide from L-arginine. nNOS is calcium/calmodulin dependent and has a Km = 2.0 μM for L-arginine.

Unit Definition

One unit of enzyme produces 1 nmole of nitric oxide per minute at 37 °C in 50 mM HEPES, pH 7.4, containing 5 μM oxyhemoglobin, 1 mM CaCl2, 20 μg/ml calmodulin, 0.1 mM NADPH, 50 μM arginine, 12 μM tetrahydrobiopterin, and 170 μM DTT.

Physical form

Solution in 50 mM HEPES, pH 7.4, with 20% glycerol, 100 mM NaCl and 10 μM tetrahydrobiopterin.

Storage Class Code

12 - Non Combustible Liquids

Blockade of monoamine transporters by cocaine should not necessarily lead to certain observed consequences of cocaine administration, including increased firing of ventral mesencephalic dopamine (DA) neurons and accompanying impulse-stimulated release of DA in the forebrain and cortex. Accordingly, we hypothesize

Nitric oxide (NO) is a multifunctional signaling molecule involved in regulating vascular tone and tissue oxygenation. It is also an important cytoprotective agent against ischemia-reperfusion injury (IRI). Enhancing NO bioavailability via exogenous NO synthases (NOSs) and L-arginine promotes conversation to
