English: The mechanism proposes that the initial binding of reverse gyrase to the DNA induces an unwinding of about 20 base pairs; after ATP binding, the bubble is rewound to about 10 base pairs, and the topoisomerase IA domain is able to introduce positive supercoils during strand passage. The enzyme is released from the DNA strand upon ATP hydrolysis, and the process can be repeated elsewhere along the DNA strand.
