Comparison of structure similarity Z-score of all vRdPs.

Individual vRdP structures are introduced by a PBD code-strain and they are assigned to a virus species. Note that structure similarity Z-score is high among vRdPs originating from viruses classified in the same genus (see genus Enterovirus (written in bold) as the best example). Structural similarity is somewhat lower but still high among vRdPs from viruses classified in the same family (see family Picornaviridae (written in italic) as the best example). Structural similarity of vRdPs from viruses classified in different families is significantly lower and is decreasing with excepted phylogenetic relationship. Compare all other families to family Picornaviridae.
