title: [Wide-angle x-ray scattering comparison of the structure of crystalline cytochrome c and cytochrome c in solution].
abstract: Large-angle X-ray diffuse scattering has been used for studying the conformational changes in cytochrome c during its transition from crystal into solution and during a change of the electron state of the heme. It has been found that the structure of cytochrome c in solution differs from its structure in crystal by a shift of the chain fragment in the region of 60-77 amino acid residues. The studies of the oxidized, reduced and cyanoforms of protein in solution have not revealed noticeable changes in the protein structure.
