Flexibility and rigidity of left-handed Z-DNA
Nucleic Acids Symposium Series
|January 1, 1983
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.
