Figure 3.

CSPs in L11 due to addition of RNA (red) and thiostrepton (green). The amide ¹H and ¹⁵N resonance shifts have been mapped and combined as Euclidian distances between peak maxima taking into account the gyromagnetic ratio of proton and nitrogen (in ¹H p.p.m.). Missing bars indicate prolines or amide resonances that have not been assigned or could not be traced back for L11 in complex. The L11 interaction sites are indicated in red for the RNA (>1.0 p.p.m.) and green for thiostrepton (>0.3 p.p.m.) on the combined ribbon/surface representation of the L11–RNA complex (26) on the right.
