Electrogenic ion pumps
Electrogenic ion pumps convert chemical, reduction-oxidation, or light energy- into ion concentration differences across all living cells. They are the engines that run cells. In this text, Dr LungerExpand

Transport mechanism of hydrophobic ions through lipid bilayer membranes
SummaryEvidence is presented that the transport of lipid-soluble ions through bilayer membranes occurs in three distinct steps: (1) adsorption to the membranesolution interface; (2) passage over anExpand

Electrical capacity of black lipid films and of lipid bilayers made from monolayers.
Planar bilayer membranes were formed from monolayers of a series of mono-unsaturated monoglycerides and lecithins. The hydrocarbon thickness of these membranes, as calculated from the electricalExpand

The rate constants of valinomycin-mediated ion transport through thin lipid membranes.
Electrical relaxation experiments have been performed with phosphatidylinositol bilayer membranes in the presence of the ion carrier valinomycin. After a sudden change of the voltage a relaxation ofExpand

Formation of large, ion-permeable membrane channels by the matrix protein (porin) of Escherichia coli.
One of the major proteins of the outer membrane of Escherichia coli, the matrix protein (porin), has been isolated by detergent solubilisation. When the protein is added in concentrations of theExpand

Effects of surface charge on the conductance of the gramicidin channel.
The electric conductance of the cation-permeable gramicidin channel in negatively charged phosphatidylserine membranes has been studied. At low electrolyte concentrations the single-channelExpand

Polarized infrared absorption of Na+/K+-ATPase studied by attenuated total reflection spectroscopy.
Na+/K+-ATPase can be isolated from the outer medulla of mammalian kidney in the form of flat membrane fragments containing the enzyme in a density of 10(3)-10(4) protein molecules per microm2Expand

Charge translocation by the Na,K-pump: I. Kinetics of local field changes studied by time-resolved fluorescence measurements
SummaryMembrane fragments containing a high density of Na, K-ATPase can be noncovalently labeled with amphiphilic styryl dyes (e.g., RH 421). Phosphorylation of the Na,K-ATPase by ATP in the presenceExpand
