Figure 7From: Functional correlation of bacterial LuxS with their quaternary associations: interface analysis of the structure networksRepresentation of Multiple sequence alignment (using ClustalW) within class IV. The "persistent hub" and the four connecting residues are highlighted in the figure with coloured lines; the green arrow indicates the "persistent hub" and the red arrows indicate the connecting residues and are numbered arbitrarily from 1 to 4. Residue 2 and 3 are completely conserved within the class whereas residue 4 is partially conserved. However the "persistent hub" and the residue 1 are completely conserved within class IV excluding m1psy. The region marked in the orange box indicates the residues present in the mini-triad for class IV; the mini-triad sequence being absent from m1the.Back to article page
