Fibrin is further stabilized by binding calcium ions (Ca2+). Note here that the inclusion of dashes on the left and right of the sequences indicates that these residues are attached to other residues not shown. In other words, there are no terminal amino and carboxyl ends. Which of the following stretches of amino acids in fibrins sequence could facilitate the binding of calcium ions?

-Asp-Glu-Thr-

-Lys-Arg-Ser-

-His-Gly-Pro-

-Met-Val-Ile-

-Gly-Trp-Phe-
