Hello all!!

I am required to mutate one of the atom of a protein (pdb file) with some groups of atoms. Pymol features us to mutate a residu with another amino acid, but I cannot mutate an atom with some other group that are not amino acids. So, how can I do it. Please help.

Also I want to know the theory behind the mutation of residue done by pymol.
