Outer membrane protein G: Engineering a quiet pore for biosensing.

Bacterial outer membrane porins have a robust beta-barrel structure and therefore show potential for use as stochastic sensors based on single-molecule detection. The monomeric porin OmpG is especially attractive compared with multisubunit proteins because appropriate modifications of the pore can be easily achieved by mutagenesis. However, the gating of OmpG causes transient current blockades ...

Structure of outer membrane protein G by solution NMR spectroscopy.

The bacterial outer membrane protein G (OmpG), a monomeric pH-gated porin, was overexpressed in Escherichia coli and refolded in beta-octyl glucoside micelles. After transfer into dodecylphosphocholine micelles, the solution structure of OmpG was determined by solution NMR spectroscopy at pH 6.3. Complete backbone assignments were obtained for 234 of 280 residues based on CA, CB, and CO connect...

Cloning and expression of Brucella outer membrane protein 36kDa (OMP2b) in E. coli

Background & Objective: Brucellosis is an important zoonotic disease of economic significance. Brucella species are gram-negative, facultative intracellular bacteria, and are capable of replicating in the phagosomes of macrophages. They cause infection in several animal species and humans. Prevention of new diseases and diagnosis of cases infected with the organism are both essential for eradic...

Pseudomonas aeruginosa outer membrane protein F: structural role and relationship to the Escherichia coli OmpA protein.

A Pseudomonas aeruginosa outer membrane protein F-deficient omega-insertion mutant strain H636, in contrast to its protein F-sufficient parent strain H103, was unable to grow on unsupplemented Proteose Peptone no. 2 broth (Difco Laboratories, Detroit, Mich.). Addition of high concentrations of NaCl, KCl, glucose, sucrose, or potassium succinate permitted growth of strain H636 at rates approachi...

Evaluation of immunogenicity and protective efficacy of a liposome containing Brucella abortus S19 outer membrane protein in BALB/c mice

The use of liposome as an adjuvant and a vaccine carrier has been cited previously in the literature. It has also been shown to be effective in enhancing the immunogenicity of vaccine candidates. BALB/c mice immunized subcutaneously with outer membrane protein (OMP) of Brucella abortus S19 vaccine strain entrapped in a commercial cationic liposome (S19-OMP-liposome) for vaccine delivery, showed...
