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).[1] This enzyme catalyses the following chemical reaction
- ATP-dependent breakage, passage and rejoining of double-stranded DNA
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 5.99.1.2 DNA topoisomerase).
