Cryo-EM structures of the S. cerevisiae condensin holo complex reveal that ATP binding triggers exchange of the two HEAT-repeat subunits bound to the SMC ATPase head domains, potentially leading to an interconversion of DNA-binding sites in the catalytic core of condensin that might form the basis of its DNA translocation and loop-extrusion activities.
