DNA topoisomerases as molecular targets for anticancer drugs [PDF]

open access: yesJournal 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-Topology Simplification by Topoisomerases

open access: yesMolecules, 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 participate in fragility of the oncogene RET. [PDF]

open access: yesPLoS 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 ...

Condensin and topoisomerases cooperate to relieve topological stress at stalled replication forks [PDF]

open access: yesNature Communications
Resolving complex topological structures at replication forks is essential for faithful DNA replication, yet the underlying mechanisms remain poorly understood.

Topoisomerases as Targets for Novel Drug Discovery [PDF]

open access: yesPharmaceuticals
DNA topoisomerases (topo) are essential enzymes that maintain the integrity of the genome by regulating the topological state of DNA during replication, transcription, recombination and repair [...]

Two-Dimensional Gel Electrophoresis to Study the Activity of Type IIA Topoisomerases on Plasmid Replication Intermediates

open access: yesBiology, 2021
DNA topoisomerases are the enzymes that regulate DNA topology in all living cells. Since the discovery and purification of ω (omega), when the first were topoisomerase identified, the function of many topoisomerases has been examined.

Archaea: A Gold Mine for Topoisomerase Diversity

open access: yesFrontiers 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 ...

Transcription facilitated genome-wide recruitment of topoisomerase I and DNA gyrase. [PDF]

open access: yesPLoS Genetics, 2017
Movement of the transcription machinery along a template alters DNA topology resulting in the accumulation of supercoils in DNA. The positive supercoils generated ahead of transcribing RNA polymerase (RNAP) and the negative supercoils accumulating behind

Structural study of Topoisomerase IV-DNA-Levofloxacin complexes from Streptococcus pneumoniae [PDF]

open access: yesE3S Web of Conferences, 2019
S. pneumoniae is an important pathogen causing pulmonary infection, acute otitis media and purulent meningitis in infants and children. Type II topoisomerases are enzymes that play essential roles in DNA replication, chromosome segregation and ...
