1I9F - PubMed Abstract:
The RSG-1.2 peptide was selected for specific binding to the Rev response element RNA, as the natural Rev peptide does. The RSG-1.2 sequence has features incompatible with the helical structure of the bound Rev peptide, indicating that it must bind in a different conformation. The binding of the RSG-1.2 peptide to the Rev response element RNA was characterized using multinuclear, multidimensional NMR. The RSG-1.2 peptide is shown to bind with the N-terminal segment of the peptide along the major groove in an extended conformation and turn preceding a C-terminal helical segment, which crosses the RNA groove in the region widened by the presence of purine-purine base pairs. These features make the details of the bound state rather different than that of the Rev peptide which targets the same RNA sequence binding as a single helix along the groove axis. These studies further demonstrate the versatility of arginine-rich peptides in recognition of specific RNA elements and the lack of conserved structural features in the bound state.
