3.6.5.4	Mg2+	required, role of a magnesium ion during the GDP and GTP-bound states, overview. The binding of magnesium in the nucleotide site causes the reorientation of the beta-and gamma-phosphate groups toward the jaws of the P-loop and stabilizes the binding of the nucleotide, creating a network of hydrogen and water-bridge interactions	757514
