Predicted secondary structures of RRE mutants used in the study. Arrows indicate nucleotide difference in constructs compared with RRE IIB (wild type). RRE IIB* depicts peptide-bound secondary structure of RRE IIB, based on the NMR (PDB access code 1ETF, 1ETG, (8)) model of RRE IIB/Rev33–55 complex.
