Model for the peptoid–TAR RNA complex. The five essential residues of the peptoid bind the major groove of TAR RNA. The three Narg residues are in green, the Nphe residue is in blue, and the Nahg residue is in red. The TAR RNA structure is shown as a surface representation with the negative charges (primarily associated with the backbone phosphates) highlighted in yellow. Note the high occupancy of the groove, with the extended Nahg residue reaching across the duplex to make contact with phosphates opposite the bulge.
