WebA phosphodiesterase ( PDE) is an enzyme that breaks a phosphodiester bond. Usually, phosphodiesterase refers to cyclic nucleotide phosphodiesterases, which have great clinical significance and are described below. WebOverdrying of DNA can also break the phosphodiester bond in DNA and result in nicks. Nicking endonuclease enzymes can assist with this process. A single-stranded break (nick) in DNA can be formed by the hydrolysis and subsequent removal of a phosphate group within the helical backbone.

Web2. The 3' hydroxyl group forms a bond to the phosphorus atom of the free nucleotide closest to the 5' oxygen atom. Meanwhile, the bond between the first phosphorus atom and the oxygen atom linking it to the next phosphate group breaks. 3. A new phosphodiester bond now joins the two nucleotides. A pyrophosphate group has been liberated. WebIndividual nucleoside triphosphates combine with each other by covalent bonds known as 5ʹ-3ʹ phosphodiester bonds, or linkages whereby the phosphate group attached to the 5ʹ carbon of the sugar of one nucleotide bonds to the hydroxyl group of the 3ʹ carbon of the sugar of the next nucleotide.
