Fig. 4From: Analyses on clustering of the conserved residues at protein-RNA interfaces and its application in binding site identificationPlots of Ms,cons versus Ms,int for all protein-RNA complexes according to the three conserved residue definitions of gradually more stringent levels: the conserved residue with sequence entropy lower than the average value (<s > int) of the interface where it occurs (a), lower than half of the average value (<s > int/2) (b), and equal to 0.0, namely, the fully conserved residue (c), respectivelyBack to article page
