Figure 3. The Calcium Binding SiteStereo view of the calcium binding site in α2LG5 in a similar view as Figure 2. The calcium ion is shown as a pink sphere. Residues coordinating to the calcium ion are labeled. Hydrogen bonds to the sulfate ion (see text) are shown as grey lines. A water molecule is also bound to the calcium ion but is not shown for clarity. The electron density shown is a difference Fourier map of the Sm derivative calculated with the final model phases and contoured at 10σ.
