We study here the PDE5A catalytic fragment formed of amino acid residues from the 535th to the 860th [23]. In the inhibition, we talk about the Sildenafil mostly, because it's the most known (active ingredient in the Viagra®).<br \>

The only catalytic fragment is effective, so the regulations sites and the dimerization to a trimeric enzyme are useless for the catalytic activity. Moreover, this catalytic moiety has the same activity that the wild-type enzyme, so maybe the enzyme is monomeric in the cell [24].
