CC -!- FUNCTION: Topoisomerase IV is essential for chromosome segregation. It
CC relaxes supercoiled DNA. Performs the decatenation events required
CC during the replication of a circular DNA molecule. {ECO:0000255|HAMAP-
CC Rule:MF_00938}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP-dependent breakage, passage and rejoining of double-
CC stranded DNA.; EC=5.6.2.2; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_00938};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00938};
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00938};
CC Name=Ca(2+); Xref=ChEBI:CHEBI:29108;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00938};
CC Note=Binds two Mg(2+) per subunit. The magnesium ions form salt bridges
CC with both the protein and the DNA. Can also accept other divalent metal
CC cations, such as Mn(2+) or Ca(2+). {ECO:0000255|HAMAP-Rule:MF_00938};
CC -!- SUBUNIT: Heterotetramer composed of ParC and ParE. {ECO:0000255|HAMAP-
CC Rule:MF_00938}.
CC -!- SIMILARITY: Belongs to the type II topoisomerase family. ParE type 1
CC subfamily. {ECO:0000255|HAMAP-Rule:MF_00938}.
