WebAll organisms must duplicate their DNA with extraordinary accurancy before either cell division. In this section, we explore how an elaborate “replication machine” accomplishes this accuracy, while duplicating DNA at rate more high as 1000 nucleotides per secondly. A phosphodiesterase is an enzyme that catalyzes the hydrolysis of phosphodiester bonds, for instance a bond in a molecule of cyclic AMP or cyclic GMP. An enzyme that plays an important role in the repair of oxidative DNA damage is the 3'-phosphodiesterase. During the replication of DNA, there is a hole … See more In chemistry, a phosphodiester bond occurs when exactly two of the hydroxyl groups (−OH) in phosphoric acid react with hydroxyl groups on other molecules to form two ester bonds. The "bond" involves this linkage … See more • Phosphodiesterase • Phosphodiesterase inhibitor • DNA replication, DNA, ATP • Teichoic acid, DNase I • PDE5 See more

WebPhosphodiesterases(PDEs) are a group of enzymes that catalyze the breakdown of cAMP or cGMP. A number of PDEs have been investigated as potential therapeutic targets in neurodegenerative diseases and schizophrenia (Reneerkens et al., 2009). From a diagnostic standpoint, PDE10A is highly expressed in the brain, particularly in the striatal MSNs.
