Abstract
All 36 ribose proton resonances and most of the base proton resonances of the hexanucleoside pentaphosphate AUAUAU have been assigned unequivocally using 2D J-resolved spectroscopy, spin echo correlated spectroscopy (SECSY) and 2D NOE spectroscopy (NOESY). The NMR parameters of AUAUAU are compared with those of smaller fragments that contain methylated adenine bases: m62AU, m62AUm62A, m62AUm62AU and m62AUm62AUm62A. Previous studies on this series of compounds have shown that in all these cases purine-pyrimidine-purine sequences prefer to adopt a mixture of states which have as common feature that the interior pyrimidine residues are bulged out, whereas the purine residues stack upon each other. Chemical shift data, proton-proton coupling constants, as well as the observation of imino-proton resonances for AUAUAU show unambiguously that upon lowering the temperature the high-temperature "bulged out" situation reverts to a normal A-RNA-like double helix.
