A theoretical-computational study of phosphodiester bond cleavage kinetics as a function of the temperature

Chemphyschem. 2024 Feb 19:e202300952. doi: 10.1002/cphc.202300952. Online ahead of print.ABSTRACTThe hydrolysis of the phosphodiester bond is an important chemical reaction involved in several biological processes. Here, we study the cleavage of this bond by means of a theoretical-computational method in a model system, the dineopentyl phosphate. By such an approach, we reconstructed the kinetics and related thermodynamics of this chemical reaction along an isochore. In particular, we evaluated the kinetic constants of all the reaction steps within a wide range of temperatures, mostly corresponding to conditions where no experimental measures are available due to the extremely slow kinetics. Our results, in good agreement with the experimental data, show the robustness of our theoretical-computational methodology which can be easily extended to more complex systems.PMID:38372713 | DOI:10.1002/cphc.202300952
