Docking of the NcdT436S C-terminus onto the motor domain. The C-terminal seven visible residues (NSCKMTK) after helix α6 (green) of chain B pack into a groove formed by the C-terminus of helix α4, N terminus of strand β8 of the central β-sheet, and N-terminus of the neck helix. The C-terminus of chain A (see Figure 6A) projects away from the motor domain and quickly becomes disordered.
