Figure 7.

Zoom on the disulfide linkage of the optimized conformers of cFEE. Two views of each structure are reported. (A, C) left-handed disulfide bridge and (B, D) right-handed disulfide bridge. The distance between the Cα atoms belonging to Cys¹ and Cys⁶ residues is reported in green broken lines of which the length (in Å) is also mentioned. The values of the five torsion angles defining the conformation of each disulfide bridge are mentioned at the right side of the representations (A) and (C). See text for details.
