It will not do what you expect. There is no "magical way" for pdb2gmx to
determine HIS protonation. The best it can do is calculate potential H-bonding
and assign protons from there; and there is no guarantee it will be "correct"
or fit your expectations. You should really determine what criteria to choose
for histidine protonation state and assign them manually for best effect.
Justin already answered this question in a different way. Perhaps there is a
language barrier/problem involved?
