Figure 15-4: Equilibrium and non-equilibrium structure in the 5' UTR of MS2 RNA responsible for the transient translation of the A-protein gene. In panel C the folding intermediate is shown that allows translation. In panel B the final structure is depicted that is translationally inactive. Both structures are phylogenetically conserved in the E. coli leviviruses (95). LDI: long-distance interaction, SD: Shine-Dalgarno sequence, UCS: upstream complementary sequence. For convenience the UCS nts are shaded. For simplicity, potential structure involving the start codon and surrounding has not been drawn.(for better image quality, click here for tif image, which may be quite large; may also require screen refreshing plus special software to view; or view larger tif in separate window)
