Function[PDE9A_HUMAN] Hydrolyzes the second messenger cGMP, which is a key regulator of many important physiological processes.[1] Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedThe phosphodiesterases (PDEs) are metal ion-dependent enzymes that regulate cellular signaling by metabolic inactivation of the ubiquitous second messengers cAMP and cGMP. In this role, the PDEs are involved in many biological and metabolic processes and are proven targets of successful drugs for the treatments of a wide range of diseases. However, because of the rapidity of the hydrolysis reaction, an experimental knowledge of the enzymatic mechanisms of the PDEs at the atomic level is still lacking. Here, we report the structures of reaction intermediates accumulated at the reaction steady state in PDE9/crystal and preserved by freeze-trapping. These structures reveal the catalytic process of a PDE and explain the substrate specificity of PDE9 in an actual reaction and the cation requirements of PDEs in general. Structural basis for the catalytic mechanism of human phosphodiesterase 9.,Liu S, Mansour MN, Dillman KS, Perez JR, Danley DE, Aeed PA, Simons SP, Lemotte PK, Menniti FS Proc Natl Acad Sci U S A. 2008 Sep 9;105(36):13309-14. Epub 2008 Aug 29. PMID:18757755[2] From MEDLINE®/PubMed®, a database of the U.S. National Library of Medicine. See AlsoReferences
