Problem:
I am familiar with the Jmol, Rasmol and PyMoL softwares, and was recently introduced to BioBlender. However, I am completely unaware if any of these programs (or others) are capable of loading a .pdb and allowing for the change in a particular amino acid, to ultimately visualize the change in tertiary structure caused by that substitution.
Question: Are any programs capable of performing an amino acid substitution on a molecule loaded by .pdb and showing the change in tertiary structure?
