Journal ArticleDOI
Influence of membrane structure on the kinetics of carrier-mediated ion transport through lipid bilayers
TL;DR: The stability constant K = kR/kD of the ion-carrier complex as well as the translocation rate constants kS and kMS were found to depend strongly on the polar headgroup of the lipid.
Journal ArticleDOI
Mutations affecting pore formation by haemolysin from Escherichia coli.
TL;DR: A model for the pore-forming structure of E. coli haemolysin is proposed, which includes a deletion mutant which retained all three hydrophobic domains but had lost amino acids 498–830 was entirely inactive in pore formation, whereas a shorter deletion led to a mutants which formed abnormal minipores.
Journal ArticleDOI
Permeability properties of the porin of spinach leaf peroxisomes
TL;DR: The results indicate that the peroxisomal channel does not form a general diffusion pore similarly to known eukaryotic porins, but has specific properties comparable to specific and inducible porins which have been characterized in some gram-negative bacteria.
Journal ArticleDOI
Pore formation by the mitochondrial porin of rat brain in lipid bilayer membranes.
TL;DR: The incorporation of rat-brain porin into artificial lipid bilayer membranes showed that it is able to form pores with an average single-channel conductance of 400 pS in 0.1 M KCI, and the pores were found to be voltage-dependent and switched to substrates at higher transmembrane potentials.
Journal ArticleDOI
Interaction of poly(ethylene-glycols) with air-water interfaces and lipid monolayers: investigations on surface pressure and surface potential.
TL;DR: Measurements of the surface potential and surface pressure demonstrate that PEGs interact with the air-water and lipid-water interfaces, and show that the effects due to lipid and PEG are not always additive and that the polymer's effect is distinct for the two lipids.
