FIGURE 3. A, plots of k[cat] versus pH for N-acetylation of
glyphosate by R7 ( ) and R7-Y118F ( ) GAT.
The pK[1] and pK[2] values shown on the graphs refer to the
acidic and basic limbs of the profiles, respectively. See
"Experimental Procedures" for experimental conditions and
theoretical fits. B, proposed chemical mechanism for
N-acetylation of glyphosate by GAT.
