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_00936}.
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_00936};
CC   -!- SUBUNIT: Heterotetramer composed of ParC and ParE. {ECO:0000255|HAMAP-
CC       Rule:MF_00936}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000255|HAMAP-Rule:MF_00936};
CC       Peripheral membrane protein {ECO:0000255|HAMAP-Rule:MF_00936}.
CC   -!- SIMILARITY: Belongs to the type II topoisomerase GyrA/ParC subunit
CC       family. ParC type 1 subfamily. {ECO:0000255|HAMAP-Rule:MF_00936}.
