Abstract

The infrared absorption and vibrational circular dichroism (VCD) spectra of buffered aqueous solutions of cytidylyl-(3'-5')-guanosine (5'(CG)3') and guanylyl-(3'-5')-cytidine (5'(GC)3') are reported. Under low ionic strength conditions, these dinucleotides exhibit VCD features that can be predicted qualitatively from structural data of (CG)2 and (GC)2 sequences of poly(dG-dC).poly(dG-dC), using the exciton model for infrared VCD intensities.

摘要

报道了胞苷酰-(3'-5')-鸟苷(5'(CG)3')和鸟苷酰-(3'-5')-胞苷(5'(GC)3')缓冲水溶液的红外吸收光谱和振动圆二色性(VCD)光谱。在低离子强度条件下，利用红外VCD强度的激子模型，这些二核苷酸表现出的VCD特征可根据聚(dG-dC).聚(dG-dC)的(CG)2和(GC)2序列的结构数据进行定性预测。
