WebApr 28, 2016 · What is a Phosphodiester bond? A phospodiester bond is a covalent bond in which a phosphate group joins adjacent carbons through ester linkages. The bond is the result of a condensation reaction between a hydroxyl group of two sugar groups and a phosphate group. WebA phosphatase performs the reverse event of severing the phosphate bond in a protein. The action of the phosphatase is thermodynamically favorable (though might require activation) because the phosphate bond on the protein is still far from equilibrium. 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 between the phosphates in the backbone left by DN… reactivity pictures
