Figure 2

Frequency of motifs in the 5′UTR regions of stable and unstable mRNAs. RMES scores for all 5-nt motifs are plotted for the most stable (x-axis) and unstable mRNAs (y-axis) at the four growth rates (0.10, 0.20, 0.40 and 0.63 h⁻¹, respectively). Exceptional motifs have either low (underrepresented motifs) or high (overrepresented motifs) scores. Exceptional motifs distant from the diagonal line of the scatter plot display different patterns of exceptionality in stable and unstable mRNAs.
