- †TEH – TBP, Endonuclease and Hyperthermophile chromosomal protein SAC7D containing structures (excluded)
- ‡TC – TBP and CAP containing structures (excluded)
- * RNA oligomers contain Uracil (U) instead of Thymine (T). d(U)-containing steps are not included for the DNA datasets. The CA/TG step was classified as having BII conformation, if either the Cytosine or the Thymine base or both were observed to have the backbone torsion angle values ε - ζ > 0.
