Chem. PDE3 is often referred to as the cGMP-inhibited PDE because, despite PDE3's ability to catalyse the hydrolysis of both cyclic nucleotides, cGMP inhibits cAMP hydrolysis competitively, because The 7 max for cAMP is 10-fold higher and the substrate affinity for cGMP is much higher than for cAMP (Keravis and Lugnier, 2012; Degerman . The phosphodiesterases (PDEs) are a family of enzymes that hydrolyze 3′, 5′-cyclic nucleotide monophosphates into their respective 5′-monophosphates.

PDE3A PDE3B Cloning and Expression. The production of cAMP and cGMP are regulated by a molecule called nitric oxide, and their function is to help regulate physiological processes by decreasing the levels of calcium in the cell. Phosphodiesterase is a ubiquitous enzyme that catalyses the hydrolysis of phosphodiester bonds. Has a preference for cGMP as a substrate. The action of PDE3 isoenzymes is implicated in myriad physiological processes including cardiovascular functions, lipolysis, carbohydrate metabolism, insulin secretion, and platelet disaggregation. PDE3 is clinically significant because of its role in regulating heart muscle, vascular smooth muscle and platelet aggregation. 3 Phosphodiesterase 4D3 and Protein Phosphatases 1 and 2a.
