Interaction of protein molecules with a linear polyelectrolyte in solution

Abstract

The polarized luminescence method was used to analyze changes in the synamic properties of protein (lysozyme) molecules interacting with polymer chains of polymethacrylic acid in water and in water-salt solutions and participating in processes of complex formation. The irregular mode of distribution of protein molecules between polyelectrolyte chains is shown: some parts of the polymethacrylic acid are compactly filled with protein, while other parts remain unfilled. Conditions of protein-polyelectrolyte complex formation have been determined ,as well as structural particularities making for greater stability of these complexes.
