Thanks for the reply Dr. Justin.
I have also thinking of the same possibility but to further confirm, I am
sending the link for the plot of the distance between the COM of ligand
binding pocket and COM of ligand molecule, please find some time to have a
look at the plot and let me know if it seems a feasible behaviour during a
