Protein

DNA topoisomerase 4 subunit B

Gene

parE

Organism
Rickettsia felis (strain ATCC VR-1525 / URRWXCal2) (Rickettsia azadi)
Status
Reviewed-Annotation score: 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.UniRule annotation

Catalytic activityi

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

Cofactori

Mg2+UniRule annotation, Mn2+UniRule annotation, Ca2+UniRule annotationNote: 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+ or Ca2+.UniRule annotation

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
