RNA topoisomerase is prevalent in all domains of life and associates with polyribosomes in animals [PDF]
DNA Topoisomerases are essential to resolve topological problems during DNA metabolism in all species. However, the prevalence and function of RNA topoisomerases remain uncertain.

Anti-topoisomerase drugs as potent inducers of chromosomal aberrations
DNA topoisomerases catalyze topological changes in DNA that are essential for normal cell cycle progression and therefore they are a preferential target for the development of anticancer drugs.

Fluorescently labeled circular DNA molecules for DNA topology and topoisomerases [PDF]
DNA topology plays essential roles in several fundamental biological processes, such as DNA replication, recombination, and transcription. Typically agarose gel electrophoresis is employed to study DNA topology.

Determination of the Primary Molecular Target of 1,2,4-Triazole-Ciprofloxacin Hybrids [PDF]
We have synthesized and examined the antibacterial activity, toxicity and affinity towards bacterial type II topoisomerases of a series of 1,2,4-triazole-ciprofloxacin hybrids.

DNA topoisomerases in mtDNA maintenance and ageing.
DNA topoisomerases pass DNA strands through each other, a function essential for all DNA metabolic processes that create supercoils or entanglements of DNA. Topoisomerases play an ambivalent role in nuclear genome maintenance: Deficiency compromises gene

DNA topoisomerase inhibitors: biflavonoids from Ouratea species
Topoisomerase inhibitors are agents with anticancer activity. 7"-O-Methyl-agathisflavone (I) and amentoflavone (II) are biflavonoids and were isolated from the Brazilian plants Ouratea hexasperma and O. semiserrata, respectively.

Clerocidin selectively modifies the gyrase-DNA gate to induce irreversible and reversible DNA damage [PDF]
Clerocidin (CL), a microbial diterpenoid, reacts with DNA via its epoxide group and stimulates DNA cleavage by type II DNA topoisomerases. The molecular basis of CL action is poorly understood.

An Experimental Framework to Examine the Influence of Promoter Architecture and Genomic Context on Gene Expression [PDF]
Transcription is a fundamental process of gene expression. Information stored in DNA is transcribed into different types of mobile RNA, which play a role in various essential processes of the cell, e.g. translation.

Controlled rotation mechanism of DNA strand exchange by the Hin serine recombinase. [PDF]
DNA strand exchange by serine recombinases has been proposed to occur by a large-scale rotation of halves of the recombinase tetramer. Here we provide the first direct physical evidence for the subunit rotation mechanism for the Hin serine invertase ...
