Adaptive laboratory evolution of chorismate synthase knockouts

We used RNA-seq to profile E. coli K-12 MG1655 strains subjected to adaptive laboratory evolution after chorismate synthase knockouts. Either isochorismate synthase (menF) or isochorismate synthase AND chorismate lyase (ubiC) was deleted from a strain of E. coli K-12 MG1655 that had already been previously adapted for growth on glucose minimal media. RNA-seq profiles of the original glucose-adapted strain, the 2 deletion strains, and 4 laboratory-evolved strains from each deletion are included in duplicate. ubiC catalyzes the first committed step of ubiquinone synthesis, an important molecule for the electron transport chain. Thus, these experiments allowed assessment of cellular adaptations to restore energy metabolism capability. Overall design: Growth of E. coli was performed with biological duplicates. Total RNA was extracted from mid-log phase culture for RNA-Seq library preparation.
