Exploring the genetic landscape of ciprofloxacin-induced DNA supercompaction in Escherichia coli

Krister Vikedal, Natalia Berges, Ida Mathilde Marstein Riisnæs, Synnøve Brandt Ræder, Jørgen Vildershøj Bjørnholt, Magnar Bjørås, Kirsten Skarstad, Emily Helgesen, James Alexander Booth

This study identifies novel genes involved in ciprofloxacin-induced DNA supercompaction in E. coli using high-content imaging and machine learning.

The RecBCD complex interacts directly with the DNA sliding clamp in Escherichia coli

Ida Mathilde Marstein Riisnæs, Synnøve Brandt Ræder, Signe Simonsen, Krister Vikedal, Paul Hoff Backe, Line Johnsen, Magnar Bjørås, James Alexander Booth, Birthe Brandt Kragelund, Kirsten Skarstad, Emily Helgesen

This paper identifies a direct interaction between the RecBCD complex and the DNA sliding clamp in E. coli, showing its role in DNA repair and survival after DNA damage.

RecN and RecA orchestrate an ordered DNA supercompaction response following ciprofloxacin exposure in Escherichia coli

Krister Vikedal, Synnøve Brandt Ræder, Ida Mathilde Marstein Riisnæs, Magnar Bjørås, James Alexander Booth, Kirsten Skarstad, Emily Helgesen

This study shows that ciprofloxacin induces DNA supercompaction in E. coli, requiring RecN and dependent on RecA, as part of a DNA damage response.
