Lipid-polypeptide interactions in bilayer lipid membranes
The Journal of Membrane Biology, 1972The modifications of the electrical properties of bilayer lipid membranes (BLM) composed of cholesterol and an ionic surfactant upon interaction with charged polypeptides were studied. The addition of 10(-8) M polylysine (Ps(+)) to one side of anionic cholesterol dodecylphosphate BLM increases the specific membrane conductance over 1000-fold (from 10 ...

Multiscale modeling of lipids and lipid bilayers
European Biophysics Journal, 2005A multiscale modeling approach is applied for simulations of lipids and lipid assemblies on mesoscale. First, molecular dynamics simulation of initially disordered system of lipid molecules in water within all-atomic model was carried out. On the next stage, structural data obtained from the molecular dynamics (MD) simulation were used to build a ...

Lipid Bilayer Electropermeabilization
2004In the majority of cells, under normal physiological conditions, there exists a transmembrane potential difference of about several tens of millivolts. This means that the electric field in biomembranes is rather high, approximately 105 V/cm. With a further increase in the electric field, biomembranes undergo changes that lead to a drastic (by 5-7 ...

Proton permeation of lipid bilayers
Journal of Bioenergetics and Biomembranes, 1987Proton permeation of the lipid bilayer barrier has two unique features. First, permeability coefficients measured at neutral pH ranges are six to seven orders of magnitude greater than expected from knowledge of other monovalent cations. Second, proton conductance across planar lipid bilayers varies at most by a factor of 10 when pH is varied from near
