RNase E resolves toxic condensates by counteracting phase separation of Type II RhlB helicases

Stéphane Hausmann, Johan Geiser, Oscar Vadas, Sylvain Guex-Crosier, Diego González, Martina Valentini

The paper identifies a Type II RhlB helicase in Pseudomonas aeruginosa that forms toxic condensates, which are resolved by RNase E through antagonizing phase separation.

Intrinsic features of the RNase E membrane targeting sequence specify RNA degradosome organisation and activity

Sandra Amandine Marie Geslain, George Edward Allen, Johan Geiser, Peter Redder, Martina Valentini

This study investigates the role of the RNase E membrane targeting sequence in bacterial RNA degradosome organization and activity, showing its importance for foci morphology, virulence, and transcriptome regulation.

Intrinsically disordered regions regulate RhlE RNA helicase functions in bacteria

Stéphane Hausmann, Johan Geiser, George Edward Allen, Sandra Amandine Marie Geslain, Martina Valentini

The paper shows that intrinsically disordered regions (IDRs) in RhlE RNA helicases regulate their functional specificity and subcellular localization in Pseudomonas aeruginosa.
