Journal ArticleDOI
Formation of large, ion-permeable membrane channels by the matrix protein (porin) of Escherichia coli.
TL;DR: One of the major proteins of the outer membrane of Escherichia coli, the matrix protein (porin), has been isolated by detergent solubilisation and the findings are consistent with the assumption that the protein forms large aqueous channels in the membrane.
Journal ArticleDOI
Permeation of hydrophilic solutes through mitochondrial outer membranes: review on mitochondrial porins
Journal ArticleDOI

TL;DR: The structure reported here represents the protein-conducting channel of the mitochondrial outer membrane of mitochondria, which mediates integration of proteins into and translocation across the lipid bilayer.
Journal ArticleDOI
Reversible electrical breakdown of lipid bilayer membranes: a charge-pulse relaxation study.
TL;DR: Charge-pulse experiments were performed with lipid bilayer membranes from oxidized cholesterol/n-decane at relatively high voltages at relatively low voltages, where the membranes show an irreversible mechanical rupture if the membrane is charged to voltages on the order of 300 mV, which is correlated with the reversible electrical breakdown of the lipid bilayers membrane.
Journal ArticleDOI
Electrical capacity of black lipid films and of lipid bilayers made from monolayers.
TL;DR: Planar bilayer membranes were formed from monolayers of a series of mono-unsaturated monoglycerides and lecithins and showed a negligible voltage dependence, whereas the Cm increased significantly at a voltage of 150 mV in the case of Mueller-Rudin-type monoolein films with n-decane as a solvent.
