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.


NONH for all modes of transport

Nitric oxide (NO) is an important cytoprotective agent against ischemia and reperfusion injury (IRI). Enhancing NO bioavailability via exogen NO synthases (NOSs) and L-arginine promotes conversation to NO, circumventing the problem of nonfunctioning NOSs under hypoxic and acidic conditions. In...
