Última Distribution and biological role of the oligopeptide-binding protein (OppA) in Xanthomonas species Genet. Mol. Biol. Oshiro,Elisa E.; Tavares,Milene B.; Suzuki,Celso F.; Pimenta,Daniel C.; Angeli,Claudia B.; Oliveira,Julio C.F. de; Ferro,Maria I.T.; Ferreira,Luis C.S.; Ferreira,Rita C.C.. In this study we investigated the prevalence of the oppA gene, encoding the oligopeptide binding protein (OppA) of the major bacterial oligopeptide uptake system (Opp), in different species of the genus Xanthomonas. The oppA gene was detected in two Xanthomonas axonopodis strains among eight tested Xanthomonas species. The generation of an isogenic oppA-knockout derivative of the Xac 306 strain, showed that the OppA protein neither plays a relevant role in oligopeptide uptake nor contributes to the infectivity and multiplication of the bacterial strain in leaves of sweet orange (Citrus sinensis) and Rangpur lime (Citrus limonia). Taken together these results suggest that the oppA gene has a recent evolutionary history in the genus and does not contribute...

Bacillus subtilis and some of its close relatives have a long history of industrial and biotechnological applications. Search for antigen expression systems based on recombinant B. subtilis strains sounds attractive both by the extensive genetic knowledge and the lack of an outer membrane, which simplify the secretion and purification of heterologous proteins. More recently, genetically modified B. subtilis spores have been described as indestructible delivery vehicles for vaccine antigens. Nonetheless both production and delivery of antigens by B. subtilis strains face some inherent obstacles, as unstable gene expression and reduced immunogenicity that, otherwise, can be overcome by already available gene technology approaches. In the present review we... Tipo: Info:eu-repo/semantics/article Palavras-chave: Vaccines; Bacillus subtilis; Immunization; Protein expression.
