Fig. 4. Geometric analysis of the disulfides in AtFN3K.
(A) Distances and dihedral values labeled for the disulfide bridges between Cys32-Cys32 and Cys236-Cys236 between chain A and chain B. The angle (Cβ-Sγ-Sγ) is shown with a green dashed line. The dihedrals are shown with dashed line colored in black. PyMOL version 2.3 (87) was used to calculate the distances and the dihedral angles. (B) Distribution of the Cα-Cα distance and χ3 angle (Cβ-Sγ- Sγ- Cβ) for PDB structures with resolution less than 1.5 Å. The data was retrieved from (65). Values for the Cys32-Cys32 and Cys236-Cys236 disulfides in AtFN3K is represented by the purple vertical lines.
