There had been an enduring discrepancy between theoretical and observed measurement of the DNA linking number (∆Lk) constrained by nucleosomes. Here the authors provide measurements of the ∆Lk constrained by individual nucleosomes in native chrom

Condensin, an SMC (structural maintenance of chromosomes) protein complex, extrudes DNA loops using an ATP-dependent mechanism that remains to be elucidated. Here, we show how condensin activity alters the topology of the interacting DNA. High conden

SUMMARYCondensin extrudes DNA loops using an ATP-dependent mechanism that remains to be elucidated. Here, we show how condensin activity alters the topology of the interacting DNA. High condensin concentrations restrain DNA positive supercoils. Howev

Most bacterial cells have a motor enzyme termed DNA gyrase, which is a type-2 topoisomerase that reduces the linking number (Lk) of DNA. The supercoiling energy generated by gyrase is essential to maintain the bacterial chromosome architecture and re
