Table 1a :

Structures for which the helical axis is best described by a single-kink line.
Sigma2 of a single-kink line is only slightly smaller (< 0.2) than for the next best model(s). All structures have 13 or more base pairs and, therefore, an unambigious classification as single-kink structure is possible, in principle, even though the goodness-of-fit difference to the next-best model is small.
The structures are listed by kink angle alpha (a).

Number of structures: 30
