DNA topoisomerase (ATP-hydrolysing) (EC 5.99.1.3 type II DNA topoisomerase DNA-gyrase deoxyribonucleate topoisomerase deoxyribonucleic topoisomerase topoisomerase DNA topoisomerase II) is an enzyme with system name DNA topoisomerase (ATP-hydrolysing). This enzyme catalyses the following chemical reaction ATP-dependent breakage passage and rejoining of double-stranded DNAThe enzyme can introduce negative superhelical turns into double-stranded circular DNA.
