Orchestrated long-distance gene activation by a ParB-like BisD-CTP DNA clamp in low-frequency transfer competence development in Pseudomonas putida

Hammam Antar, Nicolas Carraro, Hanna Budny, Stephan Gruber, Jan Roelof van der Meer

This study shows BisD, a ParB-like protein, coordinates gene activation and DNA segregation in ICEclc transfer competence development in Pseudomonas putida.

A LexA-like repressor and global H-NS-like regulators enable the fine-tuning of R-tailocin expression in environmental Pseudomonas

Clara Margot Heiman, Hammam Antar, Florian Fournès, Christoph Keel, Jordan Vacheron

The paper identifies regulators that control R-tailocin expression in Pseudomonas protegens CHA0, showing how DNA damage activates these genes through LexA-like and H-NS proteins.

DNA supercoiling enhances DNA condensation by ParB proteins

Alejandro Martín-González, Miloš Tišma, Brian T. Analikwu, Anders Barth, Richard Janissen, Hammam Antar, Gianluca Kemps, Stephan Gruber, Cees Dekker

This study shows DNA supercoiling enhances ParB-DNA condensation, forming partition complexes at lower ParB concentrations than on relaxed DNA.
