Counterion atmosphere around DNA double helix: trapping of counterions at the nanoscale
Sergiy Perepelytsya, Oleksii Zdorevskyi
DNA is strong polyelectrolyte macromolecule making metal ions (counterions) condense to a cloud around the double helix. The counterions may be localized outside the macromolecule…
Dynamics of K counterions around DNA double helix in the external electric field: a molecular dynamics study
O. O. Zdorevskyi, S. M. Perepelytsya
The structure of DNA double helix is stabilized by metal counterions condensed to a diffuse layer around the macromolecule. The dynamics of counterions in real conditions is govern…
Low-frequency vibrations of water molecules in minor groove of the DNA double helix
T. L. Bubon, S. M. Perepelytsya
The dynamics of the structured water molecules in the hydration shell of the DNA double helix is of paramount importance for the understanding of many biological mechanisms. In par…
Molecular dynamics study of the competitive binding of hydrogen peroxide and water molecules with the DNA phosphate groups
S. M. Perepelytsya, J. Uličný, S. N. Volkov
The hydrogen peroxide is present in the living cell at small concentrations that increase under the action of the heavy ion beams in the process of anticancer therapy. The interact…
Positively and negatively hydrated counterions in molecular dynamics simulations of DNA double helix
Sergiy Perepelytsya
The DNA double helix is a polyanionic macromolecule that in water solutions is neutralized by metal ions (counterions). The property of the counterions to stabilize the water netwo…
To understanding of the mechanisms of DNA deactivation in ion therapy of cancer cells
D. V. Piatnytskyi, O. O. Zdorevskyi, S. M. Perepelytsya +1
Changes in the medium of biological cell nucleus under ion beam action is considered as a possible cause of cell functioning disruption in the living body. As the most long-lived m…
