~~Dimerization of genomic RNA is directly related with the event of encapsidation and maturation of the virion.~~ The ~~initiating sequence of~~ the ~~dimerization is a short autocomplementary region in~~ the ~~hairpin loop SL1. We describe here a new solution structure of the RNA dimerization initiation site~~ (~~DIS) of HIV-1(Lai)~~. ~~NMR pulsed field-gradient spin-echo techniques and multidimensional heteronuclear NMR spectroscopy indicate that this structure is formed by two hairpins linked by six Watson-Crick GC base pairs~~. ~~Hinges between the stems and the loops are stabilized by intra and intermolecular interactions involving the A8~~, ~~A9 and A16 adenines. The coaxial alignment of the three A-type helices present in the structure~~ is ~~supported by previous crystallography analysis but~~ the ~~A8 and A9 adenines are found in a bulged in position. These data suggest the existence of an equilibrium between bulged in and bulged out conformations in solution~~.
