[gmx-users] BHIS for HIS?

[Rongliang Wu]

hello,gmx-users，
	i am trying to simulate a peptide with residue HIS, the default in pdb2gmx used HISB for HIS in both oplsaa and gromos96 force field, but i found there are HIS1,HISH,HISB etc in the rtp files, i am not sure whether HISB will suffice for my system, i intend to simulate the binding of surfactants with the peptide.
	what are the difference? 
	is there anywhere i can find the detailed description for these residues?
