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_00937}.
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_00937};
CC -!- SUBUNIT: Heterotetramer composed of ParC and ParE. {ECO:0000255|HAMAP-
CC Rule:MF_00937}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000255|HAMAP-Rule:MF_00937};
CC Peripheral membrane protein {ECO:0000255|HAMAP-Rule:MF_00937}.
CC -!- SIMILARITY: Belongs to the type II topoisomerase GyrA/ParC subunit
CC family. ParC type 2 subfamily. {ECO:0000255|HAMAP-Rule:MF_00937}.
