Coarse-grained simulation of transmembrane peptides in the gel phase [PDF]

, 2013
We use Dissipative Particle Dynamics simulations, combined with parallel tempering and umbrella sampling, to investigate the potential of mean force between model transmembrane peptides in the various phases of a lipid bilayer, including the low ...

Cholesterol's location in lipid bilayers [PDF]

Chemistry and Physics of Lipids, 2016
It is well known that cholesterol modifies the physical properties of lipid bilayers. For example, the much studied liquid-ordered Lo phase contains rapidly diffusing lipids with their acyl chains in the all trans configuration, similar to gel phase bilayers. Moreover, the Lo phase is commonly associated with cholesterol-enriched lipid rafts, which are

Lipid/water interface of galactolipid bilayers in different lyotropic liquid-crystalline phases

Frontiers in Molecular Biosciences, 2022
In this study, carried out using computational methods, the organisation of the lipid/water interface of bilayers composed of galactolipids with both α-linolenoyl acyl chains is analysed and compared in three different lyotropic liquid-crystalline phases.

Electrostatics of lipid bilayer bending

Biophysical Journal, 1997
The electrostatic contribution to spontaneous membrane curvature is calculated within Poisson-Boltzmann theory under a variety of assumptions and emphasizing parameters in the physiological range. Asymmetric surface charges, either fixed with respect to bilayer midplane area, or with respect to the lipid-water area both induce curvature but of opposite

Energetics of lipid bilayers with applications to deformations induced by inclusions [PDF]

, 2013
A new energy for the description of large deformations of lipid bilayers is formulated with mathematical rigor. This energy is derived by considering the smectic A liquid crystalline nature of lipid bilayers and the coupling between the deformations of ...

Functional tethered lipid bilayers

Reviews in Molecular Biotechnology, 2000
Our strategy to provide the structural basis for the build-up of functional tethered membranes focuses on three approaches: the first one is based on the pre-organization of a monomolecular layer of a lipopolymer at the water/air interface which is then transferred to a solid support.

The ELBA force field for coarse-grain modeling of lipid membranes [PDF]

, 2011
A new coarse-grain model for molecular dynamics simulation of lipid membranes is presented. Following a simple and conventional approach, lipid molecules are modeled by spherical sites, each representing a group of several atoms.

Correlated diffusion in lipid bilayers [PDF]

Proceedings of the National Academy of Sciences, 2021
SignificanceDynamic processes on membrane surfaces are essential for biological function. Traditionally, quantitative measurements of lipid/protein motion have been interpreted in the framework of membrane hydrodynamics. However, some recent single-molecule tracking studies have proven difficult to interpret via hydrodynamic arguments.
