FIGURE 3.
Steady-state kinetic analysis of A. thaliana chorismate mutase isoforms. Velocity versus substrate curves are shown for AtCM1 (A), AtCM2 (B), and AtCM3 (C). A and B, data were fit to the Michaelis-Menten equation. C, the Hill equation for cooperative kinetics was used for data fitting. The dashed line shows a fit to the Michaelis-Menten equation. Values shown are the average ± S.E. for an n = 3.
