Probing the catalytic sites and activation mechanism of photoreceptor phosphodiesterase using radiolabeled phosphodiesterase inhibitors. The mechanism of PDE5 drug activity” in the corpus cavernosum starts with the competitive binding with cGMP at the active site of the enzyme, intervening the neurotransmitter nitric oxide (NO) mediated sexual stimulation which eventually reverts the smooth muscle contraction via depression of the intracellular Ca2+ concentration. Structural assembly of PDE5 is a homodimer that consists of two regulatory GAF domains (GAFA and GAFB) which are the allosteric binding regions for the enzyme substrate (cGMP), phosphorylation site (at Ser92 position) which takes role in the activation mechanism of the enzyme and catalytic site located at the C-terminal end of the protein (amino acid residues: 535-860) which contains the divalent metal (Zn2+ and possibly, Mg2+) binding domain.https://generico-farmacia.eu/
