Geometry of DNA Supercoils Modulates Topoisomerase-mediated DNA Cleavage and Enzyme Response to Anticancer Drugs

Collisions with DNA tracking systems are critical for the conversion of transient topoisomerase-DNA cleavage complexes to permanent strand breaks. Since DNA is overwound ahead of tracking systems, cleavage complexes most likely to produce permanent strand breaks should be formed between topoisomeras...
