Strand-switching mechanism of Pif1 helicase induced by its collision with a G-quadruplex embedded in dsDNA

J. Valle-Orero, M. Rieu, P. L. T. Tran, A. Joubert, J.-F. Allemand, V. Croquette, J.-B. Boule

The paper develops a single-molecule assay to study Pif1 helicase resolving G-quadruplexes and reveals its strand-switching behavior affects G4 resolution efficiency.

Folding and Persistence Time of Intramolecular G-Quadruplexes Transiently Embedded in a DNA duplex

P. L. T. Tran, M. Rieu, S. Hodeib, A. Joubert, J. Ouellet, P. Alberti, A. Bugaut, J.-F. Allemand, J.-B. Boule, V. Croquette

The paper measures G4 DNA folding and persistence in double-stranded DNA using a single-molecule assay, showing G4 stability varies by genomic location and is modulated by ligands.

Fluorescence-free quantification of protein/nucleic-acid binding through single-molecule kinetic locking

M. Rieu, J. Valle-Orero, B. Ducos, J.-F. Allemand, V. Croquette

The paper introduces a fluorescence-free method called kinetic locking to quantify protein/nucleic-acid binding using single-molecule force spectroscopy, validated with E. coli RecQ helicase interactions.
