Comments [?]

Function Topoisomerase IV is essential for chromosome segregation. It relaxes supercoiled DNA. Performs the decatenation events required during the replication of a circular DNA molecule.
Catalytic activity Reaction=ATP-dependent breakage, passage and rejoining of double-stranded DNA.; EC=5.6.2.2;
Subunit Heterotetramer composed of ParC and ParE.
Similarity Belongs to the type II topoisomerase family. ParE type 1 subfamily.
