Condensin is a conserved SMC complex that uses its ATPase machinery to structure genomes, but how it does so is largely unknown. We show that condensin's ATPase has a dual role in chromosome condensation. Mutation of one ATPase site impairs condensation, while mutating the second ...
Condensin, a conserved member of the SMC protein family of ring-shaped multi-subunit protein complexes, is essential for structuring and compacting chromosomes. Despite its key role, its molecular mechanism has remained largely unknown. Here, we employ single-molecule magnetic tw ...
Every cell deals with the challenge of organising its DNA. First, the DNA needs to be compacted in size by several orders of magnitude. For example, in each human cell, 2 meters of DNA need to fit inside a micron-sized cell nucleus. Second, the DNA needs to stay accessible for ce ...
Condensin plays crucial roles in chromosome organization and compaction, but the mechanistic basis for its functions remains obscure. We used single-molecule imaging to demonstrate that Saccharomyces cerevisiae condensin is a molecular motor capable of adenosine triphosphate hydr ...
Structural maintenance of chromosomes (SMC) protein complexes, including cohesin and condensin, play key roles in the regulation of higher-order chromosome organization. Even though SMC proteins are thought to mechanistically determine the function of the complexes, their native ...
Structural maintenance of chromosome (SMC) complexes are central regulators of chromosome architecture that are essential in all domains of life. For decades, the structural biology field has been debating how these conserved protein complexes use their intricate ring-like struct ...
