Computational Mechanics Analysis of the Hidden Conformational Dynamics within a Molecular Trajectory

Abstract

In this research, the conformational dynamics of a peptide, VPAL, is investigated. Molecular Dynamic Simulation (MD) and Computational Mechanics (CM) methods are both applied to study this dynamic behaviour of VPAL. MD was used to simulate the microscopic behaviour, while the analysis was done using CM. From the analysis and the result it is observed that, at certain time scale (140ps) the conformational dynamics of VPAL dynamics is Markovian, but as the time step reduces (Δt8 < 140ps) it becomes Non-Markovian, which is clearly described by the ε-machine constructed from the dynamics at different Δt8.
