Alkaline induction of a novel gene locus, alx, in Escherichia coli.
نویسندگان
چکیده
A novel pH-regulated locus inducible over 100-fold in alkaline media was identified in Escherichia coli through screening of 93,000 Mu dI1734 (lacZ Kmr) operon fusions at pH 6.5 and pH 8.5. Four lacZ fusions that showed expression only at the higher pH were mapped at 67.5 min by P1 transduction crosses. The locus was designated alx.

Investigation of adherent-invasive E. coli in patients with Crohn\'s disease
Background: Crohn's disease and Ulcerative colitis are known as inflammatory bowel disease with high morbidity which are as a result of increasing immune responses to intestinal microbiota in genetically susceptible individuals. The association of adherent invasive Escherichia coli with Crohn's disease in human has been discussed for decades. The principal aim of this study was to assess the re...
متن کاملThe Expression of Human Granulocyte Macrophage Colony Stimulating Factor by Heat-Induction in Escherichia coli
A self-regulated high-copy number plasmid containing chloramphenicol resistant gene, for the production of recombinant proteins under the regulation of bacteriophage ?pL promoter, was constructed. The designed 5024 base pair expression plasmid contained a heat sensitive repressor cI857 coding gene to regulate the function of ?pL promoter under heat shock induction. Using the constructed vector,...
متن کاملChanges in transcriptional pausing modify the folding dynamics of the pH-responsive RNA element
Previously, we described a novel pH-responsive RNA element in Escherichia coli that resides in the 5' untranslated region of the alx gene and controls its translation in a pH-dependent manner. Under normal growth conditions, this RNA region forms a translationally inactive structure, but when transcribed under alkaline conditions, it forms an active structure producing the Alx protein. We ident...
متن کاملA DNA Vaccine against Escherichia coli O157:H7
Background: Infection with Escherichia coli O157:H7 rarely leads to bloody diarrhea and causes hemolytic uremic syndrome with renal failure that can be deadly dangerous. Intimin, translocated Intimin receptor (Tir), and enterohemorrhagic E. coli (EHEC) secreted protein A (EspA) proteins are the virulence factors expressed by locus of enterocyte effacement locus of EHEC. This bacterium needs Es...

The human granulocyte-macrophage colony stimulation factor (hGM-CSF) gene was cloned in the pET 23a( +) expression vector under the control of strong bacteriophage T7 transcription and translation signals. The hGM-CSF gene was transferred into E. coli strainBL21 (DE3)pLysS andIPTG was used for induction of GM-CSF gene. Production of the target protein was obtained as revealed by ELISA and ...
