Figure 1.
Sequences of (A) the ψ32-modified and (B) fully modified RNA hairpins corresponding to the anticodon arm of E.coli tRNAPhe. Nucleotide numbering corresponds to the full-length tRNAPhe molecule. ψ designates pseudouridine and ms2i6A designates (2-thiomethyl, N6-dimethylallyl)-adenine. ψ32-A38 base arrangements for (C) the Watson–Crick base pair and (D) the bifurcated hydrogen bond interaction.
