Figure 3
Stereoviews of the three Ca2+-binding sites in the structure of Tse3. (a) The adjacent non-EF-hand binding sites for Ca1 and Ca2 at a position surrounded by two helices (α17 and α18) and a two-stranded β-sheet. (b) The EF-hand binding site for Ca3 coordinated by amino acids on a loop that connects α27 and α28. Ca2+ ions are represented by magenta spheres and the ligated amino acids are shown as stick models.
