The emergent dynamics of double-folded randomly branching ring polymers
Elham Ghobadpour, Max Kolb, Ivan Junier +1
The statistics of randomly branching double-folded ring polymers are relevant to the secondary structure of RNA, the large-scale branching of plectonemic DNA (and thus bacterial ch…
DNA supercoiling in bacteria: state of play and challenges from a viewpoint of physics based modeling
Ivan Junier, Elham Ghobadpour, Olivier Espeli +1
DNA supercoiling is central to many fundamental processes of living organisms. Its average level along the chromosome and over time reflects the dynamic equilibrium of opposite act…
Computational tools for the multiscale analysis of Hi-C data in bacterial chromosomes
Nelle Varoquaux, Virginia S. Lioy, Frédéric Boccard +1
Just as in eukaryotes, high-throughput chromosome conformation capture (Hi-C) data have revealed nested organizations of bacterial chromosomes into overlapping interaction domains.…
Requirements for DNA-bridging proteins to act as topological barriers of the bacterial genome
Marc Joyeux, Ivan Junier
Bacterial genomes have been shown to be partitioned into several kilobases long chromosomal domains that are topologically independent from each other, meaning that change of DNA s…
Modeling supercoiled DNA interacting with an anchored cluster of proteins: towards a quantitative estimation of chromosomal DNA supercoiling
Jean-Charles Walter, Thibaut Lepage, Jérôme Dorignac +5
We investigate the measurement of DNA supercoiling density () along chromosomes using interaction frequencies between DNA and DNA-anchored clusters of proteins. Specifically, we…
A polymer model of bacterial supercoiled DNA including structural transitions of the double helix
Thibaut Lepage, Ivan Junier
DNA supercoiling, the under or overwinding of DNA, is a key physical mechanism both participating to compaction of bacterial genomes and making genomic sequences adopt various stru…
