| DNA Topoisomerases, Type II DNA Topoisomerase (ATP-Hydrolysing) | DNA Topoisomerase II | DNA Type 2 Topoisomerase | Topoisomerase II | Type II DNA Topoisomerase DNA TOPOISOMERASES that catalyze ATP-dependent breakage of both strands of DNA, passage of the unbroken strands through the breaks, and rejoining of the broken strands.
