Escherichia coli outer membrane protein K is a porin.
Protein K is an outer membrane protein found in pathogenic encapsulated strains of Escherichia coli. We present evidence here that protein K is structurally and functionally related to the E. coli K-12 porin proteins (OmpF, OmpC, and PhoE). Protein K was found to cross-react with antibody to OmpF protein and to share 8 out of 17 peptides in common with the OmpF protein. Strains that are OmpC po...
متن کاملEnvironmental regulation of Campylobacter jejuni major outer membrane protein porin expression in Escherichia coli monitored by using green fluorescent protein.
Porins allow exchanges between bacteria and their environment. In the gram-negative food-borne pathogen Campylobacter jejuni two porins, major outer membrane protein (MOMP) and Omp50, have been identified. MOMP is synthesized at a very high level under laboratory culture conditions, suggesting that its promoter functions very efficiently under these conditions. In Campylobacter samples, we obse...
متن کاملFunctional refolding of the Campylobacter jejuni MOMP (major outer membrane protein) porin by GroEL from the same species.
Functional and structural studies of outer membrane proteins from Gram-negative bacteria are frequently carried out using refolded proteins. Recombinant proteins are produced in Escherichia coli as inclusion bodies and then tediously refolded by dilution in buffered detergent solutions. In the present work, we obtained the refolding of MOMP (major outer membrane protein) from Campylobacter assi...
متن کاملSurvival ofCampylobacter jejuni in di¡erentgasmixtures
Campylobacter jejuni in fresh chilled chicken meat is known to be a major risk factor for human gastrointestinal disease. In the present study, the survival under chilled conditions of different C. jejuni strains exposed to different gas mixtures usually used for gas packaging of food was examined. Bolton broth and fresh, skinless chicken fillets were inoculated with six and four strains, respe...
متن کاملDetection of outer membrane porin protein, an imipenem influx channel, in Pseudomonas aeruginosa clinical isolates.
Decreased permeability to imipenem is the most frequent mechanism of imipenem resistance in Pseudomonas aeruginosa. We have determined the presence of OprD porin protein, an imipenem influx channel, in 70 carbapenem-resistant P. aeruginosa clinical isolates by Western blot analysis using rabbit anti-OprD polyclonal antibody. Ninety-eight percent (54 of 55 isolates) of imipenem-and meropenem-res...
