Figure S3. Rotation of the catalytic core. (A) Front view of the Unc104₃₆₂-AMPPNP map as seen in Fig. 2 A. The catalytic core is outlined by a dotted line. A straight line marks the long axis of the catalytic core, which is approximately parallel to the protofilament axis. (B) Front view of the Unc104₃₆₂-ADP map. A dashed line marks the long axis of the microtubule bound motor. The catalytic cores are related by a 5° rotation between the two states (arrow).
