Abstract

It was demonstrated in our studies that norfloxacin, a representative member of quinolone antibiotics, can indeed stabilize the gyrase-DNA complex formed during enzymatic cycle. In addition, the formation of the drug-induced complex has been firstly visualized through our atomic force microscopic examination.
