Comprehensive Bending Classification of Nucleic Acid Double Helix Structures

Table 4a:

Structures with an automatically assigned single-kink helical axis that are in fact, however, in almost all cases double-kink structures.
Sigma2 of a single-kink line is significantly smaller (> 0.2) than for the next best model(s). All structures of this Table have 12 or less base pairs. Therefore, fitting a double-kink helical axis is not possible. Visual inspection shows that almost all of these structures have in fact a double-kink helical axis even though, especially for small kink angles, a non-ambigious manual classification is impossible.
The structures are listed by kink angle alpha (a).

Number of structures: 54
