Figure 7.

(A) ¹H,¹H-NOESY, (B) ¹H,¹⁵N-TROSY and (C) HNN-COSY spectra for imino-proton correlations of the 5′-genomic end construct 5_SL5a encompassing nts 188–218. Positive contours are given in blue, negative contours in red. The imino-proton correlations are annotated using the genomic numbering. Imino-proton correlations in (A) between consecutive base pairs are shown in different colors. Included in (C) is the experimentally observed secondary structure of 5_SL5a with genomic numbering. The HNN-COSY spectrum in (C) was recorded at 298 K. Additional closing base pairs are annotated with ‘±x’. Colors of boxes are according to the correlations in (A).
