Preferential relaxation of positively supercoiled DNA by E. coli topoisomerase IV in single-molecule and ensemble measurements
We show that positively supercoiled [(+) SC] DNA is the preferred substrate for Escherichia coli topoisomerase IV (topo IV). We measured topo IV relaxation of (−) and (+) supercoils in real time on single, tethered DNA molecules to complement ensemble experiments. We find that the preference for (+)...
