Table 2 Comparison between the number of cliques and clique forming residues in monoliganded and biliganded states of LuxS

Common cliques	LuxS+SRH	LuxS+KRI	Common cliques	LuxS+2SRH	LuxS+2KRI
LuxS+SRH	44	16	LuxS+2SRH	59	15
LuxS+KRI	16	37	LuxS+2KRI	15	60
Common residues in cliques	LuxS+SRH	LuxS+KRI	Common residue in cliques	LuxS+2SRH	LuxS+2KRI
LuxS+SRH	95	60	LuxS+2SRH	90	66
LuxS+KRI	60	78	LuxS+2KRI	66	95

It is evident from the table that only a small number of common cliques are present between the mono and biliganded states (both active and inactive ligand bound forms for each) of LuxS, whereas the number of common residues constituting the cliques is quite high between them. This is indicative of the fact that majority of the common residues are rewired differently to give rise to different cliques between the active and inactive ligand bound states of the enzyme.
