Hi I want to calculate the change in free energy (electrostatic contribution only) when introducing a charge in a certain site of a protein using a single step FEP.
Should this be done with charging an inserted virtual site (a dummy atom) or a protein atom (e.g. Ca)? I noticed that in the case of the dummy atom, the Coul-14:Protein-vsite zero. I am not sure why though... Thanks a lot in advance for any feedback.
