Figure 24.

The side-chain structure of the second loop in the experimental structure of 1BDD (left) and of the UNRES kink (right) (whose profile is shown in Figure 22). The figures show the evolution of the relative torsional angles [Eq. 23], along the residue number. In both the experimental 1BDD structure and the UNRES kink, the angles η prior to the Asp37-Asp38 bonds are in the right-handed α-helical position, as shown in Figure 23b.
