TetrahydroÂ·biopterin is a cofactor for aromatic amino acid hydroxylases, AGMO, and the synthase for this molecule.
TetrahydroÂ·biopterin is a cofactor for aromatic amino acid hydroxylases, AGMO, and the synthase for this molecule. NADPH and O2 undergo redox reactions to produce citrulline and this molecule from arginine by a namesake enzyme that also binds FMN, FAD, heme, and calmodulin. This signaling molecule can be made using neuronal, cytokine-inducible, and endothelial isozymes. This cGMP- stimulating molecule can synergize with Viagra to relax penile smooth muscle and facilitate erections. The cardioprotective effects of nitroglycerine arise from its conversion to this gaseous molecule, which is necessary for vasodilation. For 10 points, name this diatomic gaseous molecule that has one fewer nitrogen than nitrous oxide.
