Factors Affecting the Folding of Pseudomonas aeruginosa OprF Porin into the One-Domain Open Conformer
Pseudomonas aeruginosa OprF is a largely monomeric outer membrane protein that allows the slow, nonspecific transmembrane diffusion of solutes. This protein folds into two different conformers, with the majority conformer folding into a two-domain conformation that has no porin activity and the minority conformer into a one-domain conformation with high porin activity and presumably consisting ...
متن کاملConservation of surface epitopes in Pseudomonas aeruginosa outer membrane porin protein OprF.
The outer membrane proteins of several prominent bacterial pathogens demonstrate substantial variation in their surface antigenic epitopes. To determine if this was also true for Pseudomonas aeruginosa outer membrane protein OprF, gene sequencing of a serotype 5 isolate was performed to permit comparison with the published serotype 12 oprF gene sequence. Only 16 nucleotide substitutions in the ...
متن کاملEpitope mapping of the Pseudomonas aeruginosa major outer membrane porin protein OprF.
The Pseudomonas aeruginosa major outer membrane protein OprF has been proposed for use as a vaccine and as a target for immunotherapeutic and diagnostic monoclonal antibodies. The well-conserved epitopes for 10 surface-reactive, OprF-specific monoclonal antibodies were localized by both overlapping peptide analysis and immunodetection of OprF peptides generated by cyanogen bromide and the prote...
متن کاملConserved OprF as a Selective Immunogen Against Pseudomonas aeruginosa
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...
متن کاملLinker-insertion mutagenesis of Pseudomonas aeruginosa outer membrane protein OprF.
The oprF gene, expressing Pseudomonas aeruginosa major outer membrane protein OprF, was subjected to semi-random linker mutagenesis by insertion of a 1.3 kb Hincll kanamycin-resistance fragment from plasmid pUC4KAPA into multiple blunt-ended restriction sites in the oprF gene. The kanamycin-resistance gene was then removed by Pstl digestion, which left a 12 nucleotide pair linker residue. Nine ...
