Figure 4

The observed KIEs on kcat/KM (empty symbols) and the intrinsic KIEs (filled symbols) on the hydride transfer in the (A) absence and (B) presence of 50 mM MgCl2. Figure A is adopted from Ref 26 with permission from ACS. The observed and intrinsic KIE values in the presence of Mg2+ are presented in Table S2 in SI. The lines are nonlinear regression of the intrinsic KIEs to Arrhenius equation (Eq 9).
