Kinetic Study of DNA Topoisomerases by Supercoiling-Dependent Fluorescence Quenching. [PDF]
DNA topoisomerases are essential enzymes for all living organisms and important targets for anticancer drugs and antibiotics. Although DNA topoisomerases have been studied extensively, steady-state kinetics has not been systematically investigated ...

Molecular Docking for the Development of Alternative Therapies against Leishmaniasis
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 ...

SUMO: A Swiss Army Knife for Eukaryotic Topoisomerases
Topoisomerases play crucial roles in DNA metabolism that include replication, transcription, recombination, and chromatin structure by manipulating DNA structures arising in double-stranded DNA.

Controlling the topology of mammalian mitochondrial DNA
The genome of mitochondria, called mtDNA, is a small circular DNA molecule present at thousands of copies per human cell. MtDNA is packaged into nucleoprotein complexes called nucleoids, and the density of mtDNA packaging affects mitochondrial gene ...

Topological Process of Splitting DNA-Links
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.

Data of transcriptional effects of the merbarone-mediated inhibition of TOP2
Type II DNA topoisomerases relax topological stress by transiently gating DNA passage in a controlled cut-and-reseal mechanism that affects both DNA strands.

Structural Basis of Gate-DNA Breakage and Resealing by Type II Topoisomerases [PDF]
ype II DNA topoisomerases are ubiquitous enzymes with essential functions in DNA replication, recombination and transcription. They change DNA topology by forming a transient covalent cleavage complex with a gate-DNA duplex that allows transport of a ...

Hot-spot consensus of fluoroquinolone-mediated DNA cleavage by gram-negative and gram-positive type II DNA topoisomerases [PDF]
Bacterial DNA gyrase and topoisomerase IV are selective targets of fluoroquinolones. Topoisomerase IV versus gyrase and Gram-positive versus Gram-negative behavior was studied based on the different recognition of DNA sequences by topoisomerase ...
