Evf, a virulence factor produced by the Drosophila pathogen Erwinia carotovora, is an S-palmitoylated protein with a new fold that binds to lipid vesicles

Erwinia carotovora are phytopathogenic Gram-negative bacteria of agronomic interest as these bacteria are responsible for fruit soft rot and use insects as dissemination vectors. The Erwinia carotovora carotovora strain 15 (Ecc15) is capable of persisting ...

Membrane pore formation by pentraxin proteins from Limulus, the American horseshoe crab

Henning Paul-Julius Stahlberg

The pentraxins are a family of highly conserved plasma proteins of metazoans known to function in immune defence. The canonical members, C-reactive protein and serum amyloid P component, have been identified in arthropods and humans. Mammalian pentraxins a ...

Imaging of G protein-coupled receptors in solid- supported planar membranes at the single molecule level

Theo Lasser, Marcel Leutenegger

Odorant receptors are an excellent example of natural superiority in specifically binding specific, small and hydrophobic molecules. They are of particular interest in the development of a sensor platform for G protein- coupled receptors (GPCRs). Odorant r ...

Regulation of the V-ATPase along the endocytic pathway occurs through reversible subunit association and membrane localization

Françoise Gisou van der Goot Grunberg, Céline Lafourcade

The lumen of endosomal organelles becomes increasingly acidic when going from the cell surface to lysosomes. Luminal pH thereby regulates important processes such as the release of internalized ligands from their receptor or the activation of lysosomal enz ...

Peptide-Phospholipid Complex Formation at Liquid-Liquid Interfaces

Hubert Girault, Manuel Alejandro Méndez Agudelo, Michel Prudent, Bin Su

Two peptides known to interact with receptors embedded in cell membranes, angiotensin III (AngIII) and Leuenkephalin(LeuEnk), were studied electrochemically at the interface formed between two immiscible electrolyte solutions modified by an adsorbed monola ...

Ultrafast Photoinduced Charge Separation in Naphthalene Diimide Based Multichromophoric Systems in Liquid Solutions and in a Lipid Membrane

Natalie Renuka Banerji, Stefan Matile, Eric Vauthey, Alexandre Fürstenberg

The photophysical properties of multichromophoric systems consisting of eight red or blue naphthalene diimides (NDIs) covalently attached to a p-octiphenyl scaffold, as well as a blue bichromophoric system with a biphenyl scaffold, have been investigated i ...

Conductive supports for combined AFM–SECM on biological membranes

Nico de Rooij, Terunobu Akiyama

Four different conductive supports are analysed regarding their suitability for combined atomic force and scanning electrochemical microscopy (AFM-SECM) on biological membranes. Highly oriented pyrolytic graphite (HOPG), MoS 2, template stripped gold, and ...

Spontaneous $ Na ^{ + } $ Transients in Individual Mitochondria of Intact Astrocytes

Michaël Unser, Dimitri Nestor Alice Van De Ville, Jean-Yves Chatton

Mitochondria in intact cells maintain low

Chemical Mapping of Ceramide Distribution in Sphingomyelin-Rich Domains in Monolayers

Dusan Vobornik

The incorporation of ceramide in phase-separated monolayers of ternary lipid mixtures has been studied by a combination of atomic force microscopy (AFM), fluorescence, and time-of-flight secondary ion mass spectrometry (ToF-SIMS). Replacement of a fraction ...

Selective removal of acetone and butan-1-ol from water with supported ionic liquid-polydimethylsiloxane membrane by pervaporation

Paul Joseph Dyson, Zhaofu Fei

The use of ionic liq.-polymer in supported ultrafiltration membrane in vacuum pervaporation has been verified. The ultrafiltration membranes were impregnated by two ionic liqs. (1-ethenyl-3-ethyl-imidazolium hexafluorophosphate and tetrapropylammonium tetr ...
