AAA_monomer_pos.png

The location and orientation of the monomer in the ring complex is defined relative to the central axis.

Three positions (P1,P2,P3) on the conserved central beta-sheet define a plane whose position is characterized by three rotations (for each axis) and the translation from the central axis.

In this case, we face a simplified docking problem in the sense that only four parameters need to be optimized instead of six as in a free docking.
