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:0000256|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:0000256|ARBA:ARBA00000185,
CC ECO:0000256|HAMAP-Rule:MF_00938};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000256|ARBA:ARBA00001946};
CC -!- SUBUNIT: Heterotetramer composed of ParC and ParE. {ECO:0000256|HAMAP-
CC Rule:MF_00938}.
CC -!- SIMILARITY: Belongs to the type II topoisomerase GyrB family.
CC {ECO:0000256|ARBA:ARBA00010708}.
CC -!- SIMILARITY: Belongs to the type II topoisomerase family. ParE type 1
CC subfamily. {ECO:0000256|HAMAP-Rule:MF_00938}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
