Solubilization, isolation, and immunochemical characterization of the major outer membrane protein from Rhodopseudomonas sphaeroides.
Solubilization of the major outer membrane protein of Rhodopseudomonas sphaeroides, and subsequent isolation, has been achieved by both non-detergent- and detergent-based methods. The protein was differentially solubilized from other outer membrane proteins in 5 M guanidine thiocyanate which was exchanged by dialysis for 7 M urea. The urea-soluble protein was purified to homogeneity by a combin...
متن کاملMolecular Characterization of a Salmonella Typhimurium Isolate from Caspian Pony
Typhoid disease or salmonellosis is a common sickness in horses. In several epidemiological studies inhospitalized horses, several serotypes of Salmonella often are predominant in nosocomial infections.Transportation, overcrowding, dehydration, oral antimicrobial therapy and infections are the risk factorswhich may activate latent or subclinical salmonellosis. In this study, t...
متن کاملCOMPARATIVE CHARACTERIZATION OF PORINS FROM SALMONELLA TYPHIO-901 AND SALMONELLA TYPHIMURIUM RA-30
Porins from Salmonella typhi 0-901 and Salmonella typhimurium Ra-30 were characterized and compared. The elution profile of porins from these salmonella species on Sepharose-48 and HPLC appear to be very similar. The findings were confirmed by the electrophoretic pattern which showed three types of porins, i.e. OmpC, OmpD and OmpF in both species. These porins appear to be similar, if not ...
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 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...
