The 1.3 A-resolution X-ray structure of the pseudoknot reveals three coaxially stacked helices buttressed by idiosyncratic base triples from loop residues. This structure represents a frameshift-stimulating state that must be deformed by the ribosome, and exhibits base-triple-adjacent pockets that could be targeted by future small-molecule therapeutics.
