it really depends a lot on what you have in the pdb. is it only coordinates
of the part you will simulate, or is it the full protein and you will
simulate just part of the pdb? if the latter, then keep the residue before
and after and change the residue names to ACE and NH2, delete the atoms that
don't exist on those capping groups. it's hard to be more specific without
knowing exactly what you are doing.
