Structural insights into the gating of DNA passage by the topoisomerase II DNA-gate [PDF]
Nature Communications, 2018 Type II DNA topoisomerases (Top2s) direct the passage of one DNA duplex through another, which is important for resolving DNA entanglements. Here the authors combine X-ray crystallography and MD simulations and present the structure of the human Top2 DNA-

DNA binding and cleavage mechanism of DNA topoisomerase VI, an evolutionary counterpart of Spo11/Wadjet/Gabija systems [PDF]
Structural DynamicsType II topoisomerases resolve DNA supercoiling and chromosome entanglements. Type IIB topoisomerases, exemplified by Top6, are used by plants and archaea to support endoreduplication and cell proliferation, respectively; homologs of Top6 subunits ...

Over-expression of Topoisomerase II Enhances Salt Stress Tolerance in Tobacco [PDF]
Frontiers in Plant Science, 2016 Topoisomerases are unique enzymes having an ability to remove or add DNA supercoils and untangle the snarled DNA. They can cut, shuffle and religate DNA strands and remove the torsional stress during DNA replication, transcription or recombination events.

Molecular Docking for the Development of Alternative Therapies against Leishmaniasis
Chemistry Proceedings, 2023 Topoisomerases play a pivotal role in regulating the topological structure of DNA during fundamental processes such as transcription, DNA repair, or DNA replication; because of this, topoisomerases are biological targets in pathogenic microorganisms or ...

Topological Process of Splitting DNA-Links
Biomath, 2022 A DNA replicon is modeled by a special type of 2-component link, called a DNA-link, in which two circles form a double helix around a trivial center core curve.
