De Franceschi, N. (author), Hoogenberg, B. (author), Katan, A.J. (author), Dekker, C. (author)Cytoskeletal protein filaments such as actin and microtubules confer mechanical support to cells and facilitate many cellular functions such as motility and division. Recent years have witnessed the development of a variety of molecular scaffolds that mimic such filaments. Indeed, filaments that are programmable and compatible with biological...journal article 2024

Tišma, M. (author), Kaljević, Jovana (author), Gruber, Stephan (author), Le, Tung B.K. (author), Dekker, C. (author)Bacterial cells require DNA segregation machinery to properly distribute a genome to both daughter cells upon division. The most common system involved in chromosome and plasmid segregation in bacteria is the ParABS system. A core protein of this system - partition protein B (ParB) - regulates chromosome organization and chromosome...review 2024

Janissen, R. (author), Barth, R. (author), Polinder, M.L. (author), van der Torre, J. (author), Dekker, C. (author)Transcription-coupled supercoiling of DNA is a key factor in chromosome compaction and the regulation of genetic processes in all domains of life. It has become common knowledge that, during transcription, the DNA-dependent RNA polymerase (RNAP) induces positive supercoiling ahead of it (downstream) and negative supercoils in its wake ...journal article 2024

(author), Michieletto, Davide (author), Gruber, Stephan (author), Dekker, C. (author)In most bacteria, chromosome segregation is driven by the ParABS system where the CTPase protein ParB loads at the parS site to trigger the formation of a large partition complex. Here, we present in vitro studies of the partition complex for Bacillus subtilis ParB, using single-molecule fluorescence microscopy and AFM imaging to show that...journal article 2023
