Title: The structure of the cohesin ATPase elucidates the mechanism of SMC-kleisin ring opening.
The authors show here that Scc2 also actively maintains cohesin on chromosomes during G1 in S. cerevisiae cells. It does so by blocking a Wapl-independent release reaction that requires opening the cohesin ring at its Smc3/Scc1 interface as well as the D loop of Smc1's ATPase.
Title: Scc2 counteracts a Wapl-independent mechanism that releases cohesin from chromosomes during G1.
The X. laevis Eco2 bound to its primary and secondary Smc3 substrates demonstrate the plasticity of the substrate-binding site, which confers substrate specificity by concerted conformational changes of the central beta-hairpin and the C-terminal extension.
