Available in PDF, EPUB and Kindle. Book excerpt: DNA Topoisomerase Protocols, I: DNA Topology and Enzymes brings together an unprecedented collection of cutting-edge experimental protocols for investigating DNA structure, topology, and DNA topoisomerase function. Described by expert experimentalists who have perfected the techniques, these unfailingly reproducible methods utilize new approaches to study changes in DNA topology (linking number, knotting, catenation, and relaxation) and DNA structure (bending), as well as to assess chromosome structure through FLP-mediated recombination and to analyze bacterial nucleoid structure. State-of-the-art protocols also detail the expression and purification of bacterial, viral, and eukaryotic DNA topoisomerases from a variety of sources, including baculovirus, and bacterial, yeast and mammalian expression systems. A companion volume, DNA Topoisomerase Protocols, v. 2: Enzymology and Drugs, provides detailed protocols to study the catalytic activities of DNA topoisomerases, as well as their specific interactions with topoisomerase-targeted antitumor and antibacterial drugs. DNA Topoisomerase Protocols, I: DNA Topology and Enzymes will be of immense value to the many basic scientists and clinicians who want better to understand and to exploit proficiently the wealth of recent discoveries about chromatin structure and its relation to gene expression, about DNA topoisomerases as the targets of antitumor and antibacterial agents, and about DNA repair.

This book was released on 2013 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gyrase introduces negative supercoils into bacterial DNA. In balance with topoisomerase I, it contributes to the maintenance of constant negative DNA supercoiling. It was shown that in Escherichia coli negative supercoil density of pBR322 plasmid is higher than in Salmonella typhimurium. One of the possible explanations of this phenomenon is a difference of DNA gyrase activity between E. coli and S. typhimurium. We developed in vitro assay of gyrase activity which has shown that DNA gyrases of E. coli and S. typhimurium have the same supercoiling end point, but E. coli gyrase works slightly faster than the S. typhimurium enzyme. To see how this rate difference influences supercoiling on the chromosome, the in vivo assay based on excision of sequence surrounded by resolvase sites has been used in various strains. The efficiency of resolvase action correlates with supercoiling density at the resolvase sites. This assay has shown that E. coli gyrB does not significantly influence supercoiling density, but E. coli gyrA relaxes the S. typhimurium chromosome. This fact can be explained by inefficient interaction of E. coli GyrA with S. typhimurium DNA.

Book excerpt: Diploma Thesis from the year 2003 in the subject Biology - Micro- and Molecular Biology, grade: 1 (A), University of Innsbruck (Institute for Microbiology), language: English, abstract: In 1885 Theodor Escherich described the gram negative bacterium Escherichia coli (E. coli) (Escherich T., Rev.1989). The gram negative rod belongs to the family of the enterobacteriaceae. It is a natural inhabitant of the human and animal intestine. E. coli can also cause diseases like diarrhea, inflammation of the urinary tract or the gall bladder. Urinary tract infections (UTIs) are one of the most common reasons for antibiotic therapy worldwide (Burman and Olsson-Liljequist, 2001). People with UTIs suffer inflammation of the urinary tract, and frequently the kidneys. Two-thirds of patients with UTIs are women (Canbaz et al. 2002). This is related in part to the shortness of the urethra, which makes colonization of the bladder by bacteria more likely. The elderly and those who undergo genitourinary operations and catheterisation are also frequent sufferers of UTIs (Orenstein and Wong, 1999). The leading causative agent of UTIs is E. coli (60-80 %), usually originating from the patients own faecal flora, followed by Staphylococcus saprophyticus (10 %), Klebsiella sp., other Gram negative bacteria and enterococci (Burman and Olsson-Liljequist, 2001). The antibiotic class most frequently prescribed to treat UTIs in Western Europe and North America is the fluoroquinolones. Fluoroquinolones are synthetic antibiotics derived from nalidixic acid. Resistance to the synthetic fluoroquinolone antibiotics is increasing among the organisms that cause UTIs.
