Sirtuins are a large enzyme family involved in installing and removing post-translational modifications involving lysine side chains. These enzymes have been of intense research interest and we now understand many details of their mechanism, although later steps of the deacetylase activity have remained a mystery. In this issue of Cell Chemical Biology, Wang et al. (2017) capture a late intermediate of SIRT2 catalysis and describe its structure.
