Title	Proteome dynamics in persisting and resuscitating bacterial cells
Description	Bacterial persister cells become transiently tolerant to antibiotics by restraining their growth and metabolic activity. Detailed molecular characterization of bacterial persistence is hindered by low count of persisting cells and the need for their isolation. Here we used sustained addition of stable isotope-labeled lysine to selectively label the proteome of hipA-induced persisting and hipB-induced resuscitating E. coli cells in minimal medium after antibiotic treatment. Time-resolved, 24-hour measurement of label incorporation allowed detection of more than 500 newly synthetized proteins in persister cells, demonstrating low but widespread protein synthesis during persistence. Many essential proteins were newly synthesized; several ribosome-associated proteins showed unusually high synthesis levels and are involved in maintenance of persistence. At the onset of resuscitation, cells synthesized ABC transporters, restored translation machinery and resumed metabolism by inducing glycolysis and biosynthesis of amino acids. This dataset provides an unprecedented insight into the processes governing persistence and resuscitation of bacterial cells.
