title: Recycling cohesin rings by deacetylation.
abstract: In this issue of Molecular Cell, Beckouët et al. (2010) and Borges et al. (2010) identify the enzyme responsible for cohesin deacetylation in anaphase and show that de novo acetylation is required for cohesion establishment in the next cell cycle.
