摘要

DNA双链（A-， B-和Z-DNA）的结构检测表明，伪旋转相位角P与扭转角δH （H4'- c4 '- c3 '- h3 '）呈正相关。这样的P - δH图反映了三种DNA双链的结构特征。由于δH扭转角可以通过核磁共振测量，因此P和δH之间的线性相关性为预测核苷和核酸的糖皱性提供了一种有用的方法。

A positive correlation between the pseudorotational phase angle P and the δ_H torsion angle (H4'-C4'-C3'-H3') in nucleosides and nucleic acids.

Examination of structures of DNA duplexes (A-, B-, and Z-DNA) showed a positive correlation between the pseudorotational phase angle P and the torsion angle δ_H (H4'-C4'-C3'-H3'). Such a P - δ_H plot reflects the structural features of the three types of DNA duplexes. Since the δ_H torsion angle can be measured by nuclear magnetic resonance, the linear correlation between P and δ_H provides a useful method for predicting the sugar pucker of nucleosides and nucleic acids.
