Relative orientation angles at dimer interfaces.

<p>Three relative angles are calculated to describe dimer configurations: <i>β</i> describes the position of binding of monomer B to the reference structure monomer A given as the rotation of monomer B around the z-axis of monomer A. The angle <i>ϕ</i> defines the rotation of monomer B around its’ own z-axis (z’) and <i>χ</i> = (180° + <i>β</i> − <i>ϕ</i>)<i>mod</i>360 describes the position of binding of monomer A to monomer B.
