Topology of the outer membrane phospholipase A of Salmonella typhimurium.
The outer membrane phospholipase A (OMPLA) of Enterobacteriaceae has been proposed to span the membrane 14 times as antiparallel amphipathic beta-strands, thereby exposing seven loops to the cell surface. We have employed the epitope insertion method to probe the topology of OMPLA of Salmonella typhimurium. First, missense mutations were introduced at various positions in the pldA gene, encodin...
متن کامل[Outer membrane remodeling of Salmonella typhimurium and host innate immunity].
Pathogenic gram-negative bacteria, including Salmonella typhimurium, remodel their outer membrane to survive within host tissues and phagosomes. The remodeling includes modifications of lipid A, a membrane anchor portion of lipopolysaccharide. Lipid A modifications, such as palmitoylation, deacylation, addition of aminoarabinose, and addition of phosphoethanolamine, are beneficial for salmonell...
متن کاملCharacterization of an outer membrane protein of Salmonella enterica serovar typhimurium that confers protection against typhoid.
Typhoid caused by Salmonella enterica serovar Typhi remains a major health concern worldwide. The emergence of multidrug-resistant strains of Salmonella with increased virulence, communicability, and survivability leading to increased morbidity and mortality has further complicated its management. Currently available vaccines for typhoid have less-than-desired efficacy and certain unacceptable ...
متن کاملUltrastructure of the outer membrane of Salmonella typhimurium bacteriocin-resistant mutants deficient in the 33K protein.
Outer membrane mutants of Salmonella typhimurium deficient in one, two, or three of the 33,000-dalton (33K), 34K, and 36K outer membrane proteins (7) were studied by using thin sectioning and freeze-fracturing electron microscopy techniques. The outer concave fracture face of all mutants deficient in the 33K protein had numerous particleless patches. In contrast to all previously examined 34K t...
متن کاملIsolation, cloning, and primary structure of a cationic 16-kDa outer membrane protein of Salmonella typhimurium.
By using acid-urea polyacrylamide gel electrophoresis, two cationic proteins were found in the isolated outer membranes of Salmonella typhimurium SH5014. Also, all the other enterobacterial strains studied (five additional strains of S. typhimurium, one strain of Salmonella minnesota, and three strains of Escherichia coli K12) had those proteins. The most abundant (OMB2) was purified in prepara...
