Interaction of the plasmid-encoded quinolone resistance protein QnrA with Escherichia coli topoisomerase IV.

John H Tran1, George A Jacoby, David C Hooper.   

Abstract

Purified QnrA blocked ciprofloxacin inhibition of topoisomerase IV, just as QnrA was previously found to prevent quinolone inhibition of DNA gyrase. With a gel displacement assay, tagged QnrA was shown to bind to topoisomerase IV and its subunits in a reaction that did not depend on the presence of DNA, quinolone, or ATP.
