Figure 5A-H. Base pairing patterns for the sRNA-mRNA pairs identified by CLASH were calculated using IntaRNA software (Busch et al. 2008) and are shown (left) for frdA-RyhB (A). Point mutations and predicted sRNA seed sequences (blue shading) are indicated. (Histograms, right) Median fluorescence intensity (MFI) was assessed by FACS for mRNA-sfGFP fusions with compensatory base changes. In each case, introduction of a point mutation into an sRNA or mRNA construct (M1) is expected to reduce sRNA repression, which should be restored by combining complementary point mutants (last bar, M1-M1). A two-tailed t-test was used to calculate significance from biological triplicate cultures. *p<0.05.A-H.
