Exponentially growing E. coli cells in M9 minimal medium + 0.4 % glucose were perturbed by the addition of 1 mM amino acid or nucleotide individually, and the transcriptional responses were tracked after 10 minutes. In total, 22 metabolites were tested, including 2-4 biological replicates for each including dye-swaps. In each experiment, the reference channel for the dual channel hybridization were cells at 0 minutes before perturbation.
