Polyelectrolyte in Electric Field: Disparate Conformational …
By explicitly describing the balancing forces between PE chain dynamics, electric polarization, counterion condensation, and hydrodynamic friction, our results captured the complex effects of electric field and resolved the long-standing controversy regarding the conformational response of PEs to electric field.
Effects of an Electric Field on the Conformational Transition of …
2019年2月7日 · The effect of the electric field on the conformational properties of the protein 1BBL was investigated by molecular dynamics simulations. Our simulation results clearly capture the structural transitions of the protein sample from helix to turn or random coil conformation induced by the increasing strength of the electric field.
External electric field driven conformation transition between …
2024年7月26日 · The external electric field has emerged as a powerful tool for building molecular switches with excellent properties. In this work, we investigate the impact of an external electric field on the transition between lithium salt and electride-like molecule conformations in Li@corannulene.
Electric field-driven folding of single molecules - ScienceDirect
2024年1月1日 · We found that molecular folding/unfolding controlled by the strong electric field leads to the switch between distinct ‘unfolding’ and ‘folding’ conformations in the single-molecule junctions. The electric field-induced homoconjugated conformation provides a new through-space pathway and leads to a ∼1400% enhancement of conductance.
Effects of an Electric Field on the Conformational Transition of the ...
2021年10月22日 · In this study, we carried out MD simulations to explore the effects of alternating electric fields, varying in frequency and electric form, on the protein samples and their mutants. The conformational stability of proteins during the simulation procedure was examined by calculating the root mean square deviation (RMSD) and the root mean square ...
Electric field - Wikipedia
The electric field (lines with arrows) of a charge (+) induces surface charges (red and blue areas) on metal objects due to electrostatic induction. Electromagnetic fields are electric and magnetic fields, which may change with time, for instance when charges are in motion.

Find the electric field (magnitude and direction) a distance z above the midpoint between two equal charges + q that are a distance d apart (Figure 5.5.3). Check that your result is consistent with what you’d expect when z ≫ d. The same as part (a), only this time make the right-hand charge − q instead of + q.
Effects of an Electric Field on the Conformational Transition of the ...
2021年12月30日 · These conclusions, achieved using MD simulations, provide a theoretical understanding of the effect of the frequency and expression form of external electric fields on the conformational changes of the all-α proteins with charged residues and the guidance for anticipative applications.
Molecular Rectification through Electric Field Induced Conformational ...
2002年11月16日 · Using a simple model, we have shown that conformational changes induced by the electric field may lead to a rectifying junction. The simplest possible rectifier of this kind presents two almost isoenergetic conformations, with different conductances and dipole moments.
Electric field induced changes in protein conformation
The effect of a low strength oscillating electric field on the conformation of Bovine Serum Albumin (BSA) and Lysozyme in solution has been measured. A purpose built cell has been used to measure the real time autofluorescence and Circular Dichroism of the protein solutions exposed to electric fields of diff.
