Schematic of the Classification. The circles represent the entire pool of DNA-protein complexes. Within the circles, ovals are the different groups of DBP; orange stars are the existing families within groups. These groups vary in their size in terms of number of families present and also the number of members within each family. After our classification, one new group was realized (red oval), also the new members were added to existing families (shaded orange ovals) and also new families were realized as represented by blue stars.
