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 ATP-dependent breakage, passage and rejoining of double-stranded DNA.
Subunit Heterotetramer composed of ParC and ParE.
Subcellular location Cell membrane; Peripheral membrane protein.
Similarity Belongs to the type II topoisomerase GyrA/ParC subunit family. ParC type 1 subfamily.
