Crystal structures of the RRM from S. cerevisiae Rna15. (A) Rna15(16-111) free, (B) Rna15(16-111)-GUUGU and (C) Rna15(16-103)ht-GUUGU. The top panels show the structures in cartoon representation, secondary structures and chain termini are labelled. RNA is shown in stick representation, guanine in magenta and uracil in yellow. The bottom panels show the molecules in the same orientation but in semi-transparent surface representation. Residues that interact with the RNA are shown as sticks. In the Rna15(16-103)ht-GUUGU structure, the GU dinucleotide bound at Y21 is from a symmetry related molecule.
