Unique clique residues for the active ligand bound forms of LuxS. The unique clique forming residues in (a) LuxS+KRI w.r.t LuxS+SRH, and (b) LuxS+2KRI w.r.t LuxS+2SRH. The two subunits are given in transparent new cartoon representations and are coloured differently. The unique residues are represented as orange van der Waals spheres and the ones which are near the active sites are depicted as violet van der Waals spheres. It is evident that a larger number of unique clique forming residues are near the active sites of LuxS+2KRI.
