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

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

The DNA backbone geometry was analyzed for 96 crystal structures of oligodeoxy-nucleotides. 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 rel...

Zusammenfassung:The DNA backbone geometry was analyzed for 96 crystal structures of oligodeoxy-nucleotides. 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
