Abstract
Twelve di- and trinucleotide parameter sets representing various structural, thermodynamic or bendability-related properties of DNA were tested in the prediction of DNA curvature applying Fourier analysis on curved and straight, A/T-type or G/C-type DNA sequence motifs. The best predictions were obtained with a new consensus bendability scale created by combining a nucleosome-based and a deoxyribonuclease I-based parameter set. Geometry calculations on the same sequences showed that the helical parameters derived from NMR structures can correctly predict curvature, as distinct from the parameters derived from X-ray crystallographic analysis.
