Figure 3.

Superimposed α-carbon stereo diagrams of α_EC domain (green) and corresponding region of γ chain (red), both from human fibrinogen. The two views are 180° apart. The carbohydrate cluster shown is attached to the Asn at α_E667. The peptide Gly-Pro-Arg-Pro-amide orientation is shown as it binds to the γC domain in fragment double-D (11, 16). Note the equivalent position of calcium atoms (Upper, red and green balls behind the ligand). Figure prepared with molscript (31), bobscript (32), and raster3d (33, 34).
