Biochem/physiol Actions

NOS is responsible for the biosynthesis of nitric oxide from L-arginine. iNOS is not calcium/calmodulin dependent and has a Km = 16 μM for L-arginine.

Unit Definition

One unit will produce 1.0 μmol of nitric oxide per minute at 37 °C in 50 mM HEPES, pH 7.4, containing 1 mM arginine, 1 mM magnesium acetate, 0.15 mM NADPH, 4.5 μM oxyhemoglobin, 18 μM tetrahydrobiopterin and 180 μM DTT.

Physical form

Solution in 50 mM HEPES, pH 7.4, with 10% glycerol, 8 μM tetrahydrobiopterin
