Root mean square deviation (RMSD): The root mean square deviation (RMSD) is a measure of structural differences that are observed on superimposition of two protein structures at a different time points i.e. current position and previous position. The RMSD values for backbone atoms of each residue were calculated for entire trajectory to see the evolution of structure with time. The RMSD plot is shown in Supplementary Figure S7 where timestep is plotted on X-axis while RMSD (Å) is plotted on Y-axis
