| Abstract: | The interaction of nuclear proteins of protamine and histone with neutral and charged BLM was studied. Anion and cation detergents were used to create the surface charge. The surface density of charges in BLM was comparable with that in biomembranes. Protamine and histone increased the electroconductivity of negatively charged BLM for anions and cations correspondingly. It is suggested that the surface charge of the membrane may influence the ion transport directly and indirectly due to the interaction of the membrane structures with charged proteins present in the surrounding medium. |
