Subject: AMBER: Protonation states in Constant pH Simulations

Dear Amber Users

I apologise if my question is answered in the manual, or elsewhere on
the reflector, but I am unable to find the information I need. The
manual states the state 0 corresponds to deprotonated ASP and GLU,
protonated LYS and TYR, and doubly protonated HIS residues. I was
wondering what protonation positions the other states of HIS residues
correspond to.
