A strain of Yersinia pseudotuberculosis which harbors a 63-kilobase plasmid was found to cause a lethal infection in Swiss albino mice. The rate of infection paralleled the ability of the pathogenic organism to attach to a monolayer of HeLa cells. One novel outer membrane protein (protein 1) with a molecular weight of 140,000 was found to be associated with the possession of the 63-kilobase pla...
Introduction: Neisseria meningitidis is a major causative agent of bacterial septicemia and meningitis in human. PorA is a major component of the outer membrane of N. meningitidis and functions as a cationic Porin. This study aimed to clone and determine the expression of PorA as the first step for producing a proper antigen in a vaccine study against N. meningitidis. Methods: An approximately ...
Bdellovibrio-and-like organisms (BALOs) are predatory bacteria that prey upon Gram-negative bacteria and are taxonomically subsumed in the order Bdellovibrionales. Despite their unique lifestyle, these bacteria show remarkable genotypic diversities. The outer membrane of the predators is likely to play an important role during the recognition and invasion stage, as well as in the intraperiplasm...
Background & Objectives: Due to the importance of Pseudomonas aeruginosa in severe inpatient infections and high mortality, the need for an efficient vaccine against these bacteria is increasing. In this regard, the general outer membrane porin of the most problematic microorganism P. aeruginosa, outer membrane protein F (OprF), is a good vaccine cand...
Thin sectioning and freeze-fracture-etch of the ovine ruminal isolate Mitsuokella multacida strain 46/5(2) revealed a Gram-negative envelope ultra-structure consisting of a peptidoglycan wall overlaid by an outer membrane. Sodium-dodecyl-sulfate-polyacrylamide gel electrophoretic (SDS-PAGE) analysis of whole cells, cell envelopes and Triton X-100 extracted envelopes in combination with thin-sec...
Abstract Mitochondria are essential cellular organelles, which supply eukaryotic cells with the universal energy carrier adenosine triphosphate. These organelles feature a unique double-membrane architecture, is formed by smooth outer membrane and highly folded inner membrane. Harnessing super-resolution light electron microscopy, we investigate role of MICOS, large mitochondrial protein comple...
conclusions the results showed that the extracted omvs were conformationally stable, and there were no pyrogenic determinants in omv. also the results showed that the omv elicited high level of specific antibodies against n. meningitidis serogroup a. these results indicate that the omv obtained here, can be used as a meningococcal vaccine after further investigation. materials and methods omvs ...
The free energy of unfolding of a membrane protein from lipids into water (ΔG(o)(w,l)) describes its equilibrium thermodynamic stability. Knowing this parameter gives insight into a membrane protein's sequence-structure-energy relationships. However, there are few measures of membrane protein stability because of the technical difficulties associated with unfolded and partially folded states. H...
Antisera to the major outer membrane protein of Vibrio cholerae (molecular weight, 48,000) raised in rabbits (i) agglutinated several strains of V. cholerae and (ii) immunoprecipitated outer membrane proteins prepared from both the biotypes and serotypes of V. cholerae. Antibodies of all isotypes to the major outer membrane protein were detected in immune human sera by enzyme-linked immunosorbe...
