title: Open and Closed Questions about Open and Closed SMC.
abstract: The tripartite ring of the bacterial condensin complex Smc-ScpAB entraps DNA to separate replicated chromosomes. The cycle of ring opening and closing is dependent on ATP hydrolysis. In this issue of Structure, Kamada et al. (2017) report on the tripartite-ring structural dynamics and their role in regulating this cycle.
