title: [Effect of R plasmid on cell membrane structure in Salmonella derby].
abstract: The structure of membranes of Salmonella derby cells both containing R-plasmid and free of plasmid was studied by small- and large-angle X-ray diffraction. Reflections with interplane distances of 8 and 11 A were detected, which are typical of plasmid-carrying S. derby cells. These reflections are assumed to be due to equidistant well ordered positions of the polar groups of phosphatidylcholine and phosphatidylethanolamine molecules on membrane surface. It is also suggested that the formation of these structures is determined by peculiar hydrophilic-hydrophobic interactions of the phospholipid in membranes.
