Figure 7.

The HB interactions of G273 in (a) high salt concentration, (b) low salt concentration. (c) When Mg(1) binds to G274, a water molecule in the Mg(1)–(H2O)5 complex formed stable HB interactions with the U275 phosphate group. (d) When Mg(1) binds to G273, water molecules in Mg(1)–(H2O)5 complex formed stable HB interactions with U275 and G276 phosphate groups. Water molecules in the Mg(A1)–(H2O)6 complex also formed stable HB interaction with nearby bases and C277 and A278 phosphate groups. Green spheres indicate magnesium ions. For simplicity, some bases are removed from figures.
