The putative structures of the fibrinogen γ-chain C-terminal residue of γ387 variants. The wire-frame views show residues that are within 0.6 nm of residue γ387. The views of γ387 variants were generated with Swiss-Pdb Viewer³⁸  from the protein databank file 3fib/pdb. (A) γ387I; (B) γ387R; (C) γ387L; (D) γ387M; (E) γ387A; and (F) γ387D. Thin and thick dotted lines show putative strong H-bonds and steric hindrance, respectively.
