Effects of ciprofloxacin on plasmid DNA supercoiling of Escherichia coli topoisomerase I and gyrase mutants.

Changes in plasmid DNA supercoiling were measured following treatment of Escherichia coli cells, carrying topoisomerase mutations, with the quinolone ciprofloxacin. In quinolone-susceptible cells (top+ gyr+) as well as in topA mutants and in gyrB mutants, plasmid DNA was relaxed after the addition o...
