Murein lipoprotein is a critical outer membrane component involved in Salmonella enterica serovar typhimurium systemic infection.
Lipopolysaccharide (LPS) and Braun (murein) lipoprotein (Lpp) are major components of the outer membrane of gram-negative enteric bacteria that function as potent stimulators of inflammatory and immune responses. In a previous paper, we provided evidence that two functional copies of the lipoprotein gene (lppA and lppB) located on the chromosome of Salmonella enterica serovar Typhimurium contri...
متن کاملPilF is an outer membrane lipoprotein required for multimerization and localization of the Pseudomonas aeruginosa Type IV pilus secretin.
Type IV pili (T4P) are retractile appendages that contribute to the virulence of bacterial pathogens. PilF is a Pseudomonas aeruginosa lipoprotein that is essential for T4P biogenesis. Phenotypic characterization of a pilF mutant confirmed that T4P-mediated functions are abrogated: T4P were no longer present on the cell surface, twitching motility was abolished, and the mutant was resistant to ...
متن کاملTopology 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 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 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 ...
