Figure 9.
Solid state NMR structure of a tetrametic M2TM-M2CT complex 61 (PDB: 2L0J) shown in cartoon (left) and surface (right) representations. Cα atoms of S23 and L46 are shown as spheres. The distance between the two planes formed by the Cα atoms of S23 and L46 is 3.0 nm. The diameter of the circle outlined by the Cα atoms of S23 is 1.7 nm, and the diameter of the circle outlined by the Cα atoms of L46 is 3.0 nm.
