Was it kicked out upon crystallisation or was crystallisation possible because most of your pentamers were not fully occupied by ligand so allowing the possibility of good contacts? ;-) What was the excess of ligand? Do you know its affinity? Miguel 2007/6/24, Michal Harel > > Hi all, We have a structure of a pentamer which was crystallized from > a complex of the protein with a ligand.
