Functioni

Topoisomerase IV is essential for chromosome segregation. It relaxes supercoiled DNA. Performs the decatenation events required during the replication of a circular DNA molecule.2 Publications

Catalytic activityi

ATP-dependent breakage, passage and rejoining of double-stranded DNA.2 Publications

Enzyme regulationi

Inhibited by quinolones, such as levofloxacin.1 Publication
