Delete chains from a protein We have a docking target protein with multiple chains (A,B and C). However, I just need chain A. How can I delete the 2 other chains from the docking target protein.
If the tag r is incorrect, the easiest way is to download and install PyMOL: https://pymol.org/2/
Drap and drop your pdb file and type remove not chain A.
Then save molecule via the menu as pdb or type save some_file_name.pdb (will be in your home root folder).
