                <details>An initial homology model of S. pombe cut7 kinesin-5 motor domain based on human kinesin-5 structure (PDB 3HQD) was prepared using Modeller. The coordinates of motor bound to an alpha-beta tubulin dimer (PDB 1JFF) were rigidly fitted into the cryo-EM map using Chimera and refined by flexible fitting using Flex-EM. Structural models of loop5 and loop10 were generated using Modeller. The conformation of the neck-linker and the N-terminus were calculated using a conjugate-gradient energy minimization approach.</details>
