Molecular dynamics simulations of biomolecules: long-range electrostatic effects.
Current computer simulations of biomolecules typically make use of classical molecular dynamics methods, as a very large number (tens to hundreds of thousands) of atoms are involved over timescales of many nanoseconds. The methodology for treating short-range bonded and van der Waals interactions has matured. However, long-range electrostatic interactions still represent a bottleneck in simulat...
متن کاملMolecular dynamics simulations of electrostatic layer-by-layer self-assembly.
Electrostatic assembly of multilayered thin films through sequential adsorption of polyions in layer-by-layer fashion utilizes the strong electrostatic attraction between oppositely charged molecules. We perform molecular dynamics simulations of multilayers of flexible polyelectrolytes around a charged spherical particle. Our simulations establish that the charge reversal after each deposition ...
متن کاملSynthesis novel bis-Coumarin derivatives as potential acetylcholinestrase inhibitors: An in vitro, molecular docking, and molecular dynamics simulations study
Alzheimer's disease is an irreversible and progressive brain disorder that slowly destroys memory and thinking skills and ultimately the ability to do the simplest things and can lead to death. Cholinesterases (ChEs) play an important role in controlling cholinergic transmission, and subsequently, by inhibiting CHEs, acetylcholine levels in the brain are elevated. Coumarins have been shown to e...
متن کاملGeneralized image charge solvation model for electrostatic interactions in molecular dynamics simulations of aqueous solutions
This paper extends the image charge solvation model (ICSM) [J. Chem. Phys. 131, 154103 (2009)], a hybrid explicit/implicit method to treat electrostatic interactions in computer simulations of biomolecules formulated for spherical cavities, to prolate spheroidal and triaxial ellipsoidal cavities, designed to better accommodate non-spherical solutes in molecular dynamics (MD) simulations. In add...
متن کاملFAMUSAMM: An Algorithm for Rapid Evaluation of Electrostatic Interactions in Molecular Dynamics Simulations
Within molecular dynamics simulations of protein]solvent systems the exact evaluation of long-range Coulomb interactions is computationally demanding and becomes prohibitive for large systems. Conventional truncation methods circumvent that computational problem, but are hampered by serious artifacts concerning structure and dynamics of the simulated systems. To avoid these artifacts we have de...
