Abstract
MULTIDIMENSIONAL heteronuclear NMR has revolutionized solution structure determinations of proteins1-3. But this technique has not been applied to nucleic acids because of difficulties in the synthesis of isotopically (13C and/or 15N) labelled molecules. Here we report the application of three–dimensional heteronuclear NMR to the study of a uniformly 13C/15N or 15N–labelled RNA duplex of defined sequence. These experiments simplify resonance assignment and the analysis of proton–proton nuclear Overhauser effects4 (and therefore distance information) in the molecule. Our results show that it is now possible to determine the structures of larger and more complex RNAs using multidimensional heteronuclear NMR.Keywords
