==Catalytic Domain Of Human Phosphodiesterase 5A In Complex With Vardenafil==
-
Phosphodiesterases (PDEs) comprise a large family of enzymes that catalyze, the hydrolysis of cAMP or cGMP and are implicated in various diseases. We, describe the high-resolution crystal structures of the catalytic domains, of PDE4B, PDE4D, and PDE5A with ten different inhibitors, including the, drug candidates cilomilast and roflumilast, for respiratory diseases., These cocrystal structures reveal a common scheme of inhibitor binding to, the PDEs: (i) a hydrophobic clamp formed by highly conserved hydrophobic, residues that sandwich the inhibitor in the active site; (ii) hydrogen, bonding to an invariant glutamine that controls the orientation of, inhibitor binding. A scaffold can be readily identified for any given, inhibitor based on the formation of these two types of conserved, interactions. These structural insights will enable the design of, isoform-selective inhibitors with improved binding affinity and should, facilitate the discovery of more potent and selective PDE inhibitors for, the treatment of a variety of diseases.

== Function ==
 +
[https://www.uniprot.org/uniprot/PDE5A_HUMAN PDE5A_HUMAN] Plays a role in signal transduction by regulating the intracellular concentration of cyclic nucleotides. This phosphodiesterase catalyzes the specific hydrolysis of cGMP to 5'-GMP.
