DNA-Topology Simplification by Topoisomerases [PDF]
Molecules, 2021 The topological properties of DNA molecules, supercoiling, knotting, and catenation, are intimately connected with essential biological processes, such as gene expression, replication, recombination, and chromosome segregation. Non-trivial DNA topologies

DNA topoisomerases as molecular targets for anticancer drugs [PDF]
Journal of Enzyme Inhibition and Medicinal Chemistry, 2020 The significant role of topoisomerases in the control of DNA chain topology has been confirmed in numerous research conducted worldwide. The prevalence of these enzymes, as well as the key importance of topoisomerase in the proper functioning of cells ...

DNA topoisomerases participate in fragility of the oncogene RET. [PDF]
PLoS ONE, 2013 Fragile site breakage was previously shown to result in rearrangement of the RET oncogene, resembling the rearrangements found in thyroid cancer. Common fragile sites are specific regions of the genome with a high susceptibility to DNA breakage under ...

EcoSal Plus, 2015 DNA topoisomerases are enzymes that control the topology of DNA in all cells. There are two types, I and II, classified according to whether they make transient single- or double-stranded breaks in DNA. Their reactions generally involve the passage of a single- or double-strand segment of DNA through this transient break, stabilized by DNA-protein ...

Transcription, 2013 Chromatin is dynamically changing its structure to accommodate and control DNA-dependent processes inside of eukaryotic cells. These changes are necessarily linked to changes of DNA topology, which might itself serve as a regulatory signal to be detected by proteins.

Supercoiled DNA recognition and cleavage control in topoisomerase VI [PDF]
Nature CommunicationsType II topoisomerases modulate DNA supercoiling and resolve chromosome entanglements. Type IIB topoisomerases, exemplified by DNA topoisomerase VI (Top6), are used by plants and archaea to support endoreduplication and cell proliferation, respectively ...

Archaea: A Gold Mine for Topoisomerase Diversity
Frontiers in Microbiology, 2021 The control of DNA topology is a prerequisite for all the DNA transactions such as DNA replication, repair, recombination, and transcription. This global control is carried out by essential enzymes, named DNA-topoisomerases, that are mandatory for the ...
