Figure 3. Schematic representation depicting the detailed interactions of aluminum fluoride with Mg[2]ADP, active site residues of the catalytic subunit, water molecules and the phosphorylation site Ser from SP20. Mg2+ ions and water molecules are indicated in large and small spheres, respectively. Residues displayed in ball-and-stick representation exhibit the exact conformation and relative orientation as observed in the crystal structure; however, they have been displaced with respect to one another for clarity.
