Abstract
The local variation of torsional angles and helical parameters in Z-DNA was analyzed. The sugar phosphate backbone is fairly rigid but the angles at GpC linkage are more changeable than those at CpG linkage in order to form a variety of structures. The water channel at minor groove is important to stabilize and retain the novel Z-DNA helix.
摘要
对Z-DNA中扭转角和螺旋参数的局部变化进行了分析。糖磷酸主链相当刚性，但GpC连接处的角度比CpG连接处的角度更易变化，以便形成各种结构。小沟处的水通道对于稳定和保持新型Z-DNA螺旋很重要。
