Fig. 5
The rotation angle of a macromolecule. The left subfigure is the initial status, and the right subfigure shows the macromolecule P after rotating. The middle one is the intermediate rotation state which is only used to calculate the rotation matrix. Two linearly independent vectors can uniquely determine the angle of rotation of a macromolecule. First, the rotation angle of A0B0 to A1B1 is solved. The rotation of the macromolecule around the A1B1 axis is then determined by the vector A1C′0 and A1C′1. The rotation angle is obtained by superimposing the above two angles. In our simulation, since the overall size of the macromolecule is mostly concentrated around 120, the diameter of filaments and membranes is set to 40, and 80 respectively
