HISE is just epsilon-protonated histidine, which Gromos96 force fields call
HISB. There is no need to add any sort of parameters; they're already there.
The aminoacids.r2b file should take care of the naming translation when running
pdb2gmx. If for some reason it doesn't, just rename the residues in the
coordinate file itself.
