Structure and activity of lipid bilayer within a membrane-protein transporter

Proceedings of the National Academy of Sciences of the United States of America, 2018
Significance Membrane proteins function naturally as imbedded in the lipid bilayers of cell membranes, but isolation into homogeneous and soluble preparations is needed for many biochemical studies. Detergents, which are used traditionally to extract and

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

Reduced Lipid Bilayer Thickness Regulates the Aggregation and Cytotoxicity of Amyloid-β*

Journal of Biological Chemistry, 2017
The aggregation of amyloid-β (Aβ) on lipid bilayers has been implicated as a mechanism by which Aβ exerts its toxicity in Alzheimer's disease (AD). Lipid bilayer thinning has been observed during both oxidative stress and protein aggregation in AD, but ...

The Power of Asymmetry: Architecture and Assembly of the Gram-Negative Outer Membrane Lipid Bilayer.

Annual Review of Microbiology, 2016
Determining the chemical composition of biological materials is paramount to the study of natural phenomena. Here, we describe the composition of model gram-negative outer membranes, focusing on the predominant assembly, an asymmetrical bilayer of lipid ...

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.

On Shape Transformations and Shape Fluctuations of Cellular Compartments and Vesicles [PDF]

, 1993
We discuss the shape formation and shape transitions of simple bilayer vesicles in context with their role in biology. In the first part several classes of shape changes of vesicles of one lipid component are described and it is shown that these can be ...

A continuum model of lipid bilayers [PDF]

European Journal of Applied Mathematics, 2004
We study a one-dimensional continuum model for lipid bilayers. The system consists of water and lipid molecules; lipid molecules are represented by two ‘beads’, a head bead and a tail bead, connected by a rigid rod. We derive a simplified model for such a system, in which we only take into account the effects of entropy and hydrophilic/hydrophobic ...
