assays. F.B. performed all the mass spectrometry experiments with the help
of V.M. and S.B. in sample preparation. R.M. performed Legionella infection
experiments and prepared samples for mass spectrometry. M.A. performed
in vitro ε-NAD+ hydrolysis assays, isothermal titration calorimetry and protein
purifications for biochemistry and cryo-EM. M.M.P. and W.P.G. prepared cryo-EM
grids, collected and processed data and performed the model refinement.
J.L.-M. performed yeast experiments. S.K. performed protein purifications. D.S.
performed protein purifications and in vitro SidJ–CaM pulldown experiments.
S.B. and I.D. analysed the data and wrote the manuscript with input from all the
co-authors.
