Calculation of Free Energy Barrier for Base Flipping of Thymine Dimer Outward the DNA Double Strand Using Molecular Dynamics
, M.Sc. Thesis Sharif University of Technology ; Parsafar, Golam Abbas (Supervisor)
Abstract
Formation of Cyclobutane Pyrimidine Dimer (CPD), one of the most abundant types of damages in DNA double helices, is caused by UV radiation and plays a major role in causing skin cancer. DNA photolyase is an efficient enzyme that repairs this UV-induced damaged DNA-base. Previous studies have shown that the enzyme flips the dimer out of the DNA double helix into its binding pocket.
In this project, several nanoseconds of molecular dynamics simulations was performed to investigate the process of base flipping energetically. These simulations are consist of equilibration of repaired and damaged double strands for 3 and 8 nanoseconds respectively. All these simulations ran over NVT...
