ATP-dependent breakage, passage and rejoining of double-stranded DNA
type II DNA topoisomerase; DNA-gyrase; deoxyribonucleate topoisomerase; deoxyribonucleic topoisomerase; topoisomerase; DNA topoisomerase II;
DNA topoisomerase (ATP-hydrolysing)
The enzyme can introduce negative superhelical turns into double-stranded circular DNA. One unit has nicking-closing activity, and another catalyses super-twisting and hydrolysis of ATP (cf.EC 18.104.22.168 DNA topoisomerase).
