Deubiquitinases (DUBs) targeting Met1-linked ubiquitin chains have important functions in mammals but are barely studied in plants. Here, the authors identify rice OTUB1 as a Met1-targeting DUB, characterize the structural determinants of this activity, and show that these features are conserved in green plants.
