Nat.Struct.Biol., 5:432-436, 1998 Cited by PubMed Abstract: Retroviral genomes must dimerize to be fully infectious. Dimerization is directed by a unique RNA hairpin structure with a palindrome in its loop: hairpins of two strands first associate transiently through their loops, and then refold to a more stable, linear duplex. The structure of the initial, kissing-loop dimer from HIV-1, solved using 2D NMR, is bent and metastable, its interface being formed not only by standard basepairing between palindromes, but also by a distinctive pattern of interstrand stacking among bases at the stem-loop junctions. This creates mechanical distortions that partially melt both stems, which may facilitate spontaneous refolding of this RNA complex into linear form.
