WebMar 26, 2024 · The bond between two phosphate groups is a phosphoanhydride bond which is supposed to be a high energy bond. According to this ATP has only two high energy bonds i.e., phosphoanhydride bond and no phosphodiester bond. So, the correct answer is "0" phosphodiester bond. Note: Adenosine triphosphate (ATP) is a nucleotide spent in cells … WebMar 6, 2006 · Phosphodiester linkages, including those that join the nucleotides of DNA, are highly resistant to spontaneous hydrolysis. The rate of water attack at the phosphorus atom of phosphodiesters is known only as an upper limit, based on the hydrolysis of the dimethyl phosphate anion.
WebMar 18, 2024 · Relative to its native phosphodiester bond forming activity, the kinetic disadvantage of BF’s NP-DNA polymerase activity is approximately four orders of magnitude with F710Y, since transient k pol /K d is 3.1 µM −1 s −1 for DNA synthesis with Mg 2+ vs. 3.2 × 10 −4 µM −1 s −1 for NP-DNA synthesis with Ca 2+ . This difference is of ... WebTwo prominent mechanisms have been proposed for RNA and protein enzyme catalyzed cleavage of phosphodiester bonds in RNA: (a) intramolecular nucleophilic attack by the 2'-hydroxyl group adjacent to the reactive phosphate; and (b) intermolecular nucleophilic attack by hydroxide, or other oxyanion.
WebFeb 20, 2024 · Phosphodiester Bond is involved in the polymerization of nucleotides. When polymerization occurs, the -OH group gets attached to 3 carbon of nucleotides (sugar … 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.
