The bacterial pathogen Legionella pneumophila secretes effectors that affect protein ubiquitination within host cells, involving production of phosphoribosyl ubiquitin (PR-Ub). Here, the authors identify additional effectors that convert PR-Ub back into functional ubiquitin, thus maintaining ubiquitin homeostasis in infected cells.
