Figure 2. DNA parameters. (a) Minor groove widths
were averaged for the 10 -- 11 base-pairs between indi-
vidual protein -- DNA contact points, and are plotted
against the superhelix location. Values for X-NCP,
NCP-PA1, NCP-PA2, and NCP-PA3 are plotted against
SHLs in black, blue, green, and magenta, respectively.
The location of polyamides in each structure is indicated
by blue, green, and magenta boxes, respectively. Data
points for SHLs at which stretching occurs are circled;
the equivalent regions in the long half are indicated by
broken-line circles. (b) DNA twist angles, averaged as
in (a). The position of stretch sites is indicated as in (a).
A vertical line indicates the location of the dyad axis
(SHL 0).
