Nuclear Overhauser effects (NOEs) in yeast tRNAAsp were found for all four GU and G psi base pairs. NOEs of both reverse-Hoogsteen pairs were identified by comparison with a purine C8 deuterated sample. Several NOEs involving these resonances were also found which are clearly between single protons on adjacent base pairs. These interbase NOEs, combined with the assumption of reasonable similarity between the structure of yeast tRNAAsp and that of yeast tRNAPhe, lead to unambiguous assignment of many resonances including all the ring NH and C2 protons in the D stem. The stability of the stem at 28 degrees C, as recently deduced by Moras et al (Nature 288 669-674), from x-ray diffraction is confirmed. Assignments of the ring NH resonances of T54-A58 and of a G psi pair are made for the first time.
