Synthesized ssRNA oligonucleotide derivatives for MST

mut, mutation; N, 30-nt ssRNA oligonucleotide; nifKR, nifK mRNA; wt, wild type.

^*The 11-nt sequence of the NfiS stem-loop pairing with nifK mRNA is shown in red. The 11-nt sequence of the complementary region at the 5′ end of nifK mRNA is shown in blue. Point mutations introduced into synthesized oligonucleotide derivatives are underlined.

^†The WT N-NfiS-wt binds to the WT N-nifKR-wt whereas the compensatory mutated oligonucleotide (N-nifKR-mut11) binds to WT N-NfiS-wt more tightly, as shown in Fig. 3 B and G.
