Hi Maryam, You can easily align two proteins in Pymol to compare their structures. Read both protein structures into the same window under the action option, choose align and select which one you want. E.g align to molecule (via alpha carbons) Hope this is what you wanted J

I have a protein that its crystal structure is not known. So I used "Modeller" software to predict the structure of its closet hit. ( I can easily visualize the structure of the closet hit in PyMOL) Now I want to visualize the structure of initial protein (the one that its crystal structure was not known) based on the structure of its closest hit. I tried that with "Chimera" software using structure alignment. I would like to know if PyMoL is able to do that? Any suggestion would greatly be appreciated. Best regards Maryam
