Protein
DNA topoisomerase 4 subunit B
Gene
parE, RF_0988
Organism
Rickettsia felis (strain ATCC VR-1525 / URRWXCal2) (Rickettsia azadi)
Status
Reviewed - Annotation score: 3 out of 5 - Protein inferred from homologyi

Functioni

Topoisomerase IV is essential for chromosome segregation. It relaxes supercoiled DNA. Performs the decatenation events required during the replication of a circular DNA molecule By similarity.UniRule annotation

Catalytic activityi

ATP-dependent breakage, passage and rejoining of double-stranded DNA.UniRule annotation

Cofactori

Magnesium. Binds two Mg2+ per subunit. The magnesium ions form salt bridges with both the protein and the DNA. Can also accept other divalent metal cations, such as Mn2+ and Ca2+ By similarity.
