Figure 3

Primary isotope effects using protonated and deuterated D-glucuronate at the C-2 position are presented as double-reciprocal plots where (A) is the plot for the wild-type enzyme, (B) R414M mutant, and (C) D412N mutant. The data for the protonated substrate are represented as circles, and the values for the deuterated substrate are denoted as squares.
