All Interface amino acid clusters in one representative member from each class (I–VI). (a) CLASS I (H. influenzae), (b) CLASS II (H. pylori), (c) CLASS III (B. subtilis), (d) CLASS IV (D. radiodurans), (e) CLASS V (V. cholerae), and (f) CLASS VI (L. johnsonii), at Imin = 6%. The two subunits of the LuxS dimer are represented in different colours (chain A in white and chain B in green) by new cartoon representation. The cluster forming residues are shown in van der Waal's representation (Blue spheres and red spheres represent the residues from chain A and chain B respectively).
