Vice … WebMay 2, 2014 · DNA gyrase and topoisomerase IV control bacterial DNA topology by breaking DNA, passing duplex DNA through the break, and then resealing the break. This process is subject to reversible corruption by fluoroquinolones, antibacterials that form drug-enzyme-DNA complexes in which the DNA is broken. The … The first DNA topoisomerase was discovered in bacteria by James Wang in 1971 and was initially named ω (omega) protein; it is now called Escherichia coli (E. coli) topoisomerase I (topo I) and is a representative of the type IA family of enzymes. Subsequently, a similar activity was found in eukaryotic cells (rat … See more DNA topoisomerases (or topoisomerases) are enzymes that catalyze changes in the topological state of DNA, interconverting relaxed and supercoiled forms, linked (catenated) and unlinked species, and knotted and … See more For the non-specialist perhaps the most important aspect of topoisomerases is their role as drug targets both for antibacterial and … See more • DNA topology • Supercoil • Type I topoisomerase • Type II topoisomerase See more The double-helical structure of DNA involves the intertwining of the two polynucleotide strands around each other, which potentially … See more DNA topoisomerases are enzymes that have evolved to resolve topological problems in DNA (Table 2).
