Comprehensive Bending Classification of Nucleic Acid Double Helix Structures

Bending classification of helical axis - Straight line
(Last update: November 15, 2004)

Table 2a:

Structures for which the helical axis is best described by a straight line.
Sigma2 of the straight line is only slightly smaller (< 0.2) than for the next-best model(s). The structures are listed by the number of base pairs (bp).

Number of structures: 136
