KCl
the optimal ionic strength for both enzymes requires 100 mM KCl, with DHFR displaying 2.5fold activation and TS 4.5fold activation
Mg2+
additional information
Mg2+
-
in Tris-acetate buffers 10 mM enhances enzyme activity by some 30%
Mg2+
TS is activated 4.5fold at 10 mM MgCl2, but inhibited at higher concentrations of MgCl2. The activating effect is not additive with activation by KCl
presence of Mg2+ does not enhance reaction rates and has no impact on the transition state structure of hydride transfer
