Conformations of the sugar-phosphate backbone in helical DNA crystal structures

Biopolymers. 1997;42(1):113-24. doi: 10.1002/(sici)1097-0282(199707)42:1<113::aid-bip10>3.0.co;2-o.

Abstract

The DNA backbone geometry was analyzed for 96 crystal structures of oligodeoxynucleotides. The ranges and mean values of the torsion angles for the observed subclasses of the A-, B-, and Z-DNA conformational types were determined by analyzing distributions of the torsion angles and scattergrams relating pairs of angles.
