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