Abstract: | Outer membrane vesicles were reconstituted from phospholipids, lipopolysaccharide, and outer membrane proteins isolated from Salmonella typhimurium. The vesicles appeared to be permeable to sucrose and other small oligosaccharides only when membrane proteins were added to the reconstitution system. The size of saccharides that could pass through the vesicle membranes was found to be close to the size of saccharides that penetrate through the intact outer membrane of S. typhimurium. |
