Abstract
Nuclear Overhauser effect (NOE) measurements are reported for the nonexchangeable base and ribose 1' proton resonances of CCGGAp, ACCGGp, and ACCGGUp. The results permit assignment of these resonances to particular nucleotides in the sequences. The NOE data rule out conformations containing syn glycosidic linkages and conformations in which the purine 8 and pyrimidine 6 protons are closer to the 3' nearest-neighbor ribose 1' proton than to the 5' nearest-neighbor ribose 1' proton.
摘要
报道了CCGGAp、ACCGGp和ACCGGUp的非交换性碱基和核糖1'质子共振的核Overhauser效应（NOE）测量结果。这些结果允许将这些共振分配到序列中的特定核苷酸。NOE数据排除了包含顺式糖苷键的构象以及嘌呤8和嘧啶6质子比5'最近邻核糖1'质子更靠近3'最近邻核糖1'质子的构象。
