Exploring Biochemical Mechanisms With Hybrid Quantum Mechanics/Molecular Mechanics And Enhanced Sampling Methods, Edwin Enciso

WWU Graduate School Collection

In the field of molecular dynamics (MD), a long-standing issue is the time frame required in order to fully observe a chemical reaction. Enhanced sampling methods have been the primary way of overcoming this issue for the past 40 years. In this experiment our goal was to combine new and existing sampling methods in order to create an efficient and accurate way of retrieving kinetics data from simulations. In order to do this, we examined two test cases: the enzymes chorismate mutase and cytosine deaminase. We did this using hybrid quantum mechanics/molecular mechanics simulations coupled with enhanced sampling methods. The …
