The slowest motion modes of the PAM-absent and PAM-present systems. (a) The bottom view (left) and side view (right) of the structure of Cas1-Cas2-DNA. (b,d) The first slowest motion mode using the bottom view (a left). (c,e) The second slowest motion mode using the side view (a right). The length of cone is positively-correlated with motive magnitude, and the orientation of cone indicates motive direction.
