FIGURE 6.
Effect of MLCtide concentration on PAK2 autoactivation. A, plot of the steady-state velocities vs against substrate concentration, [S]. The solid line represents the best fitting result according to Michealis-Menten equation with KS = 292 μm, k2 = 34 s−1. B, plot of the apparent second-order rate constant A against substrate concentration, [S]. The continuous line represents the best fitting result according to Equation 5 with k+0 = 14.4 μm−1 s−1, and a fixed KS = 292 μm. C, plot of the reciprocal of the apparent second-order rate constant, A, against substrate concentration, [S]. D, plot of the intra-initiation rate constant ke against substrate concentration, [S]. The solid line represents the best fitting result with ke of 0.0254 ± 0.0007 s−1.
