The pdb file has a coordinates of a monomer.
I have used following commands to generate an assembly, or in other words to upload one more biological unit so that the protein would be a dimer:
set assembly, "" fetch 2obt, asu, async=0 set assembly, "1" fetch 2obt, assembly1, async=0
After generating the functional dimer in pymol under name
assembly1, I have an important issue that I cannot save a dimer structure in pdb file with dimer coordinates. Does anybody has an idea how to go around it or is it even possible to do that?
