Figure 1 Biosynthesis of NO. NO is generated by a class of NADPH-dependent NO synthases, which catalyze the conversion of arginine to citrulline and NO with a 1:1 stoichiometry. Three different isoenzymes have been characterized: two of them are constitutive and calcium-/calmodulin-activated (ecNOS and ncNOS), and one is an inducible, calcium-independent isoform (iNOS).
