چکیده

We report a regulation system in Escherichia coli for independent regulation of two distinct reporter genes by application of Tet repressors with different specificities. One Tet repressor variant comprises wild-type tet operator (tetO) recognition and exclusive induction with the novel inducer 4-dedimethylamino-anhydrotetracycline. The other Tet repressor variant shows tetO-4C recognition and induction with tetracycline. We demonstrate that both variants are independently active in vivo and allow selective regulation of two genes in the same cell without any cross talk.

Construction of New Genetic Tools as Alternatives for Protein Overexpression in Escherichia coli and Pseudomonas aeruginosa

Background: Pseudomonas protein expression in E. coli is known to be a setback due to signifi cant genetic variation and absence of several genetic elements in E. coli for regulation and activation of Pseudomonas proteins. Modifi cations in promoter/repressor system and shuttle plasmid maintenance have made the expression of stable and active Pseudomonas protein possible in bot...

Independent and tight regulation of transcriptional units in Escherichia coli via the LacR/O, the TetR/O and AraC/I1-I2 regulatory elements.

Based on parameters governing promoter activity and using regulatory elements of the lac, ara and tet operon transcription control sequences were composed which permit the regulation in Escherichia coli of several gene activities independently and quantitatively. The novel promoter PLtetO-1 allows the regulation of gene expression over an up to 5000-fold range with anhydrotetracycline (aTc) whe...

  Today, it is nearly 25 years past from investigation of Shiga toxigenic Escherichia coli (STEC) which is able to produce Shiga toxins and cause different gastroenteritis. Since incidence of gastroenteritis due to STEC is increasing, it's necessary to develop rapid, specific and accurate procedures like PCR. In this study, we used PCR method to detect and identify STEC in cultures of 55 Escher...
