Mutator effects in Escherichia coli caused by the expression of specific foreign genes.

چکیده
Certain genes from Lactococcus lactis and Pseudomonas aeruginosa, including the nfxB gene, generate a mutator phenotype in Escherichia coli. The results of this study, together with those of a previous study, support conservation of regulatory sequences in E. coli and P. aeruginosa and suggest that some efflux pumps prevent mutagenicity by exporting mutagenic products of metabolism.

Expression of a Chimeric Protein Containing the Catalytic Domain of Shiga-Like Toxin and Human Granulocyte Macrophage Colony-Stimulating Factor (hGM-CSF) in Escherichia coli and Its Recognition by Reciprocal Antibodies
Fusion of two genes at DNA level produces a single protein, known as a chimeric protein. Immunotoxins are chimeric proteins composed of specific cell targeting and cell killing moieties. Bacterial or plant toxins are commonly used as the killing moieties of the chimeric immunotoxins. In this investigation, the catalytic domain of Shiga-like toxin (A1) was fused to human granulocyte macrophage ...
متن کاملEffects of ackA, pta and poxB inhibition by antisense RNA on acetate excretion and recombinant beta interferon expression in Escherichia coli
Introduction: Escherichia coli (E.coli) is one of the most widely used hosts for the production of recombinant proteins. The main problem in getting high product yields and productivity is the accumulation of acetic acid (acetate) as an unwanted metabolic by-product. In this study, an antisense-based strategy as a metabolic engineering approach was employed to hamper the acetate excretion probl...

Background and Aim: Salmonella Typhi belongs to the family Enterobacteriaceae, gram-negative bacilli and causes gastrointestinal diseases such as typhoid. This bacterium has a special structure and various genes, including the ompf gene (outer membrane protein). Recent studies have shown the possibility of using ompf in the development of a diagnostic tuberculosis vaccine. Therefore, the aim of...

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...

Background and purpose: Recent studies suggest that the viable but nonculturable (VBNC) bacteria could cause inflammatory diseases. The aim of this study was to detect and investigate the expression of nuc and rfbE genes in blood samples of patients with rheumatoid arthritis (RA). Materials and methods: In this experimental study, 102 blood samples were collected from patients with RA and univ...
