PaCS-MD/MSM: Parallel Cascade Selection Molecular Dynamic Simulation in Combination with Markov State Model as an Efficient non-Bias Sampling Method

Abstract

Parallel Cascade Selection Molecular Dynamics simulation (PaCS-MD) is among the enhanced sampling methods without applying extra bias potential/force. Here we report our recent advances in applying PaCS-MD to investigate association and dissociation of protein/peptide complexes. In combination with the Markov state model (MSM), PaCS-MD/MSM exhibits its ability to predict native complex structure and calculate the binding free energy, association and dissociation rate constants of the complexes in agreement with experimental data.
