Hi all,
I want to simulate the folding process of two helix proteins in water, but I do not know how to deal with two proteins in CHARMM. For example, there will be only one set of coordinates from the PDB file for each protein, and how will I locate the two proteins? And also, what about some other problems needed to be noticed. Your suggestions are welcome.
