Figure 2: DNA bending in the NCP147 DNA. Structures (left)
and schematic representations (right) stress uniformity of
curvature in the major-groove blocks (red) (a), and alternating
shift values (b) and localization of curvature in kinks in
minor-groove blocks (c) (yellow for one representative
double-helical turn). Also indicated are the primary
bound-phosphate groups (green), the block-junction phosphate
groups (white) and the DNA axes for the NCP147 (gold) and ideal
(white) superhelices. The contributions of base-pair-step
curvature to superhelix bending are listed with base-pair
numbers (centre).
