Variability of metabolites across conditions

The variability of 101 measured metabolites is shown as relative SD(RSD) across 16 conditions (stationary phase and rich medium were not considered). The RSD is the SD across conditions normalized to the mean. Amino acids are shown in orange and nucleotides in blue. Inserts show the relationship of the growth rate with concentrations of IMP and 5-Amino-1-(5-phospho-D-ribosyl)imidazole (air). Colors indicate the experimental condition. R is the Pearson correlation coefficient of growth rates and metabolite levels. See Figure S4–S6.
