Comprehensive Bending Classification of Nucleic Acid Double Helix Structures

Slight bending (  0 ° < M <= 10 °)
Classification II (double kink: M = max(a1,a2))
(Last update: November 15, 2004)

(There are structures with 13 or more base pairs for which a double-kink helical axis is selected as the most appropriate description by the automatic approach, but the central segment consists of 0 or 1 base pairs only. In these cases the double-kink geometrical parameters make no sense. Therefore, these structures have to be viewed as single-kink structures. They are indicated by a * in the model description).

Number of structures: 226
