The interaction between bacterial lipopolysaccharides (EPS) and phospholipid cell membranes was studied by various physical methods of deep rough mutant EPS (ReEPS) of Escherichia coH incorporated in phospholipid bilayers as simple models of cell membranes. SS P-NMR spectroscopic analysis suggested that a substantial part of ReEPS is incorporated into l,2-dimyristoyl-sn-glycero-3-phosphocholine (DMPC) lipid bilayers when mixed multilamellar vesicles were prepared. Furthermore the lipid lateral diffusion coefficients measurements at various molar ratios of ReEPS/egg-PC/POPG indicated that the incorporated ReEPS reduces the diffusion coefficients of the phospholipids in the membrane. EUV formed by the ReEPS from Salmonella enterica, eventually in mixture with dilauroyl phosphatidylcholine (DEPC), have been prepared and characterized by DES, SANS and EPR. PFGSE NMR measurements have shown that water permeability through the lipid bilayer is low at room temperature. However, above a transition temperature centered at 30-35 °C, the water permeability increases. ...

From bottom to top (a) dicapryl-PC (Ciq), dimyrlstoyl-PC (C14), dipalmitoyl-PC (Cie). distearoyl-PC (Cig) and dibehenoyl-PC (C22) (b) dicapryl-PE (length of the hydrocarbon tails Cio). dilauroyl-PE (C12). dimyristoyl-PE (C14) and distearoyl-PE (Cis). The curve for dilauroyl-PC (Ci2) is not depicted since it coincides almost completely with the one for dimyrlstoyl-PC. (Redrawn from M.C. Phillips, D. Chapman, Biochim. Biophys.
