Figure 4: Surface depictions of Ku. a, Space-filling model
showing Ku bound to DNA. The model was prepared by fitting a
32-bp B DNA to the crystallographically observed duplex. DNA
extends towards the viewer to the +11 level. Ku70 is coloured
red and Ku80 orange. DNA is shown with one light grey and one
dark grey strand. b, Molecular surface representation of Ku is
coloured according to electrostatic potential, calculated using
the program GRASP44. Negative potential is coloured red and
positive potential blue.
