Roth supplemented with one hundred mM monosodium glutamate, 1 glycerol, and 1 mM ethylene glycol tetraacetic acid (EGTA) as indicated. For PA103 complementation experiments, 0.4 arabinose was added to induce RsmA or RsmF expression. Strains had been grown at 30 to an A600 of 1.0 and -galactosidase activity was determined as previously described (23). -Galactosidase activities reported within this study are averages of 3 or a lot more independent experiments and error bars correspond to SEM. Student two-tailed unpaired t tests have been performed utilizing Prism 5 GraphPad. Note. For the duration of manuscript preparation, a thesis describing identification of RsmF (designated RsmN) was published on line (34). ACKNOWLEDGMENTS. We thank Joseph Mougous (University of Washington) for providing the Hcp1 and Tse1 antisera, and Tony Romeo for insightful discussions all through these studies.
