(A) The proposed structure of the ψ-RNA. It includes: a main stem, formed by HIV-1 (LAI) coding sequences, flanking SL 1 and SL 4; SL 1, which contains the dimer initiation site, 5′-GCGCGC; SL 2, which has the 5′ splice donor site of HIV; SL 3, SL 4 and the start codon of the gag gene at positions 236–238. The circles indicate nucleotides that are involved in binding neomycin, i.e. exhibit type 1 footprinting plots. The triangles indicate nucleotides that exhibit structural changes (enhancements) in the presence of neomycin, i.e. type 2 or type 3 footprinting plots. (B) The structure of neomycin B.
