Monte Carlo simulations of polyampholyte-polyelectrolyte complexes: effect of charge sequence and strength of electrostatic interactions.
We present the results of Monte Carlo simulations of complexation between polyampholyte and polyelectrolyte chains. Polymers are modeled as bead-spring chains of charged Lennard-Jones particles each consisting of 32 monomers. Formation of a polyampholyte-polyelectrolyte complex is driven by polarization-induced attractive interactions. The complex is usually formed at the end of the polyelectro...
متن کاملAdsorbed Monomer Analog of a Common Polyelectrolyte
The monomer analog of a common water-soluble charged macromolecule shows surface tilt and cooperative adsorption that would be expected for larger surfactant molecules—the small organic ion behaves as an embryonic surfactant. Yet the organic ion competes with inorganic ions (Na, Mg, etc.) for access to the surface, and therefore its tilt increases with the size of the competing coion. Similar o...
متن کاملDesigning substrate specificity by protein engineering of electrostatic interactions.
Protein engineering of electrostatic interactions between charged substrates and complementary charged amino acids, at two different sites in the substrate binding cleft of the protease subtilisin BPN', increases kcat/Km toward complementary charged substrates (up to 1900 times) and decreases kcat/Km toward similarly charged substrates. From kinetic analysis of 16 mutants of subtilisin and the ...
متن کاملOn the monomer density of grafted polyelectrolyte brushes and their interactions.
Most of the modern theories of grafted polyelectrolyte brushes are valid only for moderate stretching of the polyelectrolyte. However, particularly at low ionic strength and high grafting densities, even a moderate charge of the polyelectrolyte can generate a strong stretching. A simple mean field model for strongly stretched grafted polyelectrolyte brushes is suggested, based on an approximate...
متن کاملElectrostatic correlations and the polyelectrolyte self energy.
We address the effects of chain connectivity on electrostaticfluctuations in polyelectrolyte solutions using a field-theoretic, renormalizedGaussian fluctuation (RGF) theory. As in simple electrolyte solutions [Z.-G. Wang,Phys. Rev. E 81, 021501 (2010)], the RGF provides a unified theory forelectrostatic fluctuations, accounting for both dielectric and charge correlationeffects in terms of the ...
