Table 2. Numbers of calcium ions and zinc ions at EF1, EF3 and EF5.

Calcium ions and zinc ions are found intermolecularly coordinated to the Asn106 residues of two adjacent ALG-2 molecules (between molecules B and C and between molecules F and G in the Ca²⁺-bound form and between molecules B and C and between molecules D and E in the Zn²⁺-bound form).
