Based on the analysis of X-ray structural data of six DNA-binding proteins, we have shown that at the microlevel (2-6 angstroms), the surface of DNA-binding proteins is close to the surface of globular proteins and has the fractal dimension D = 2.1. At the same time, at the macrolevel (greater than 6 angstroms), the surface of DNA-binding proteins differs strongly from that of globular proteins, and its surface area increases proportionally to the protein volume, although average sizes of these proteins increase proportionally to the cube root of the volume, as for similar bodies.
