POMBE CUT7 REMARK 3 KINESIN-5 MOTOR DOMAIN BASED ON HUMAN KINESIN-5 STRUCTURE (PDB REMARK 3 3HQD) WAS PREPARED USING MODELLER. THE COORDINATES OF MOTOR REMARK 3 BOUND TO AN ALPHA-BETA TUBULIN DIMER (PDB 1JFF) WERE RIGIDLY REMARK 3 FITTED INTO THE CRYO-EM MAP USING CHIMERA AND REFINED BY REMARK 3 FLEXIBLE FITTING USING FLEX-EM. STRUCTURAL MODELS OF LOOP5 AND REMARK 3 LOOP10 WERE GENERATED USING MODELLER. THE CONFORMATION OF THE REMARK 3 NECK-LINKER AND THE N-TERMINUS WERE CALCULATED USING A CONJUGATE- REMARK 3 GRADIENT ENERGY MINIMIZATION APPROACH.
