The outer membrane protein F (OmpF) is known to play an important role in the uptake of fluoroquinolone antibiotics by bacteria. In this study, the degree of binding of the fluoroquinolone antibiotic ciprofloxacin to OmpF in a lipid membrane environm

The mode of action of antimicrobial peptides (AMPs) in disrupting cell membrane bilayers is of fundamental importance in understanding the efficiency of different AMPs, which is crucial to design antibiotics with improved properties. Recent developme

Organic thin film deposition presents a multiplicity of challenges. Most notably, layer thickness control, homogeneity and subsequent characterization have been not cleared yet. Phospholipid bilayers are frequently used to model cell membranes. Bilay

Lung surfactant protein B (SP-B) is a lipophilic protein critical to lung function at ambient pressure. KL(4) is a 21-residue peptide which has successfully replaced SP-B in clinical trials of synthetic lung surfactants. CD and FTIR measurements indi

In the present work, we study the structure and the orientation of the 23 N-terminal peptide of the HIV-1 gp 41 protein (AVGIGALFLGFLGAAGSTMGARS) called FP23. The behaviour of FP23 was investigated alone at the air/water interface and inserted into v

Trichlorophenols are weak acids of high hydrophobicity and are able to transport protons across the mitochondrial membrane. Thus the proton motive force is dissipated and the ATP production decreased. In situ Fourier Transform Infrared-Attenuated Tot

The membrane location of two fragments in two different K(+)-channels, the KvAP (from Aeropyrum pernix) and the HsapBK (human) corresponding to the putative "paddle" domains, has been investigated by CD, fluorescence and NMR spectroscopy. Both domain

The bilayer phase transitions of three kinds of phospholipids, dipalmitoylphosphatidylcholine (DPPC), distearoylphosphatidylcholine (DSPC) and dihexadecylphosphatidylcholine (DHPC), in deuterium oxide (D(2)O) and hydrogen oxide (H(2)O) were observed

This study aims at characterizing the structure and some properties of phospholipid multi-lamellar vesicles (MLVs) containing the oxidized species gamma-palmitoyl-beta-(9-hydroperoxy-10,12-octadecanedienoyl)-lecithin (HPPLPC), gamma-palmitoyl-beta-(9
