Figure 3

(A) A gallery of class averages of negatively stained yKu70 particles in the absence of DNA, after 2D single particle data processing as described in Materials and Methods. The last panel on the right shows a spatial representation of 3D atomic structure of human Ku docked over a 2D class average. (B) Selected class averages of yKu particles in the presence of 580 bp DNA (1:1 molar ration Ku to DNA ends). Red arrows indicate DNA fragments protruding out from the yKu particle. Scale bars represent 10 nm.
