[Analysis of fractal properties of globular protein surfaces by means of small-angle x-ray scattering].
The "cube method" [M. Yu. Pavlov, B. A. Fedorov, Biopolymers, 22, 1507, 1983] has been used to calculate the intensity of the large-angle X-ray scattering from the volumes of several globular proteins. In the logarithmic plots of the scattered intensity curves from three of these proteins, there is a linear region at scattering angles corresponding to Bragg distances of from about 6.3 A to 21 A. This linear region possibly may be due to the fractal properties of the surfaces of these proteins on length scoles from 6.3 A to 21 A, and the fractal dimensions corresponding to the power-law scattering at these scattering angles have been evaluated.
