FIGURE 1.

Nucleotides that are important for the coat protein–AMV RNA interaction are arranged in two UGC-hairpin-RAUGC motifs. The data presented in this article are modeled after our earlier publication (Ansel-McKinney and Gehrke 1998), in which possible protein contacts, shown in color, were identified by chemical modification interference analysis. The two UGC-hairpin-RAUGC motifs form binding sites 1 and 2, which overlap at nucleotides 865–868. HP indicates hairpin. The numbers (843–846, etc.) indicate the AUGC sequences at 843–846, 865–868, and 877–881.
