NMR structures of the SIV17−50 frameshift-inducing RNA stem-loop. (A) The 20 lowest energy structures superimposed over all heavy atoms. The A-form stem is shown in blue, the purine loop nucleotides 28−30 and 38−39 are shown are in red, and the remaining loop nucleotides 31−37 are shown in green. (B) Structures superimposed over all nucleotides in the 12-nucleotide loop (G28-A39). (C) Structures superimposed over all nucleotides in the stem (nucleotides 17−27 and 40−50). (D) Stereo view of the lowest energy structure.
