- D129 (= D134) to A: in mutant PRSA1; alters the binding of divalent cations, especially magnesium. Little alteration in the affinity for ribose 5-phosphate and 27-fold decrease of the affinity for ATP. Absence of inhibition by AMP
- D220 (= D231) mutation to E: 4-fold decrease in the affinity binding for Rib-5-P in the presence of magnesium ions. In the presence of cobalt ions, it shows a 15-fold decrease in the affinity binding for Rib-5-P.; mutation to F: With magnesium or manganese ions, the affinity binding values for ATP and Rib-5-P are comparable to those of the wild-type.

The affinity binding for Rib-5-P is greatly decreased in the presence of both manganese and cobalt ions but only about 2-fold in the presence of magnesium ions.
