In that case you might want to use CNS with model_anneal.inp or model_minimize.inp, or the equivalents in phenix

Yes, it is better to have MD or energy minimization. Otherwise, with only view on the screen, we can't tell if the mutated residue would disturb ligand binding because of the side chain flexibility.
Best!

Pymol
the question is, into how much trouble do you want to get ?
MD simulations ? Energy minimisation ? Then you will need to do more than just mutate on the sreen one residue with Pymol.

Dear All,
  I am trying to mutate a single amino acid in a PDB to see if the mutant
disturbs ligand binding. Does anyone know any software that can do such work?
Thanks a lot!
