Wiktor, J.M. (author), van der Does, M. (author), Büller, L.A. (author), Sherratt, David J. (author), Dekker, C. (author)The formation of 3 single-stranded DNA overhangs is a first and essential step during homology-directed repair of double-stranded breaks (DSB) of DNA, a task that in Escherichia coli is performed by RecBCD. While this protein complex has been well characterized through in vitro single-molecule studies, it has remained elusive how end...journal article 2018

Wiktor, J.M. (author), Lesterlin, Christian (author), Sherratt, David J. (author), Dekker, C. (author)Programmable control of the cell cycle has been shown to be a powerful tool in cell-biology studies. Here, we develop a novel system for controlling the bacterial cell cycle, based on binding of CRISPR/dCas9 to the origin-of-replication locus. Initiation of replication of bacterial chromosomes is accurately regulated by the DnaA protein,...journal article 2016

Moolman, M.C. (author), Tiruvadi Krishnan, S. (author), Kerssemakers, J.W.J. (author), de Leeuw, R. (author), Lorent, V.J.F. (author), Sherratt, David J. (author), Dekker, N.H. (author)Protein-DNA complexes are one of the principal barriers the replisome encounters during replication. One such barrier is the Tus-ter complex, which is a direction dependent barrier for replication fork progression. The details concerning the dynamics of the replisome when encountering these Tus-ter barriers in the cell are poorly understood....journal article 2016

(author), Sherratt, D.J. (author), Dekker, N.H. (author)The ubiquitous sliding clamp facilitates processivity of the replicative polymerase and acts as a platform to recruit proteins involved in replication, recombination and repair. While the dynamics of the E. coli ?2-sliding clamp have been characterized in vitro, its in vivo stoichiometry and dynamics remain unclear. To probe both ?2-clamp...journal article 2014

Männik, J. (author), Wu, F. (author), Hol, F.J.H. (author), Bisicchia, P. (author), Sherratt, D.J. (author), Keymer, J.E. (author), Dekker, C. (author)Cell division in typical rod-shaped bacteria such as Escherichia coli shows a remarkable plasticity in being able to adapt to a variety of irregular cell shapes. Here, we investigate the roles of the Min system and the nucleoid-occlusion factor SlmA in supporting this adaptation. We study “squeezed” E. coli in narrow nanofabricated channels...journal article 2012
