Eukaryotic DNA Topoisomerase II (Topo II) is an essential enzyme that catalyzes the relaxation of supercoiled DNA and the segregation of newly replicated chromosomes (1 -3 ). The enzyme is highly conserved through evolution, and appears to result from the fusion of the A- and B-subunits of bacterial DNA gyrase (4 ). It has an A₂ dimeric structure, whereas the bacterial enzyme has an A₂ B₂ tetrameric arrangement.
