Figure 3.
A Michaelis-Menten plot which shows the dependence of vi/[E] on the concentration of substrate h-FUMP for the deuterium exchange reaction catalyzed by the R235A mutant of ScOMPDC at pD 8.15 (20 mM GlyGly, 20% free base), and I = 0.14 (NaCl). The solid line shows the correlation of the experimental data to eq 2 derived for Scheme 3, using the values for the kinetic parameters reported in Table 1.
