    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.UniRule annotation

    Catalytic activityi

    ATP-dependent breakage, passage and rejoining of double-stranded DNA.UniRule annotation

    Cofactori

    Magnesium. Binds two Mg2+ per subunit. The magnesium ions form salt bridges with both the protein and the DNA. Can also accept other divalent metal cations, such as Mn2+ and Ca2+.UniRule annotation
