Figure 7.

Arrhenius plots of the rate constants obtained by fitting the stopped-flow kinetics of the CH1₁ mutants (as indicated) to the tri-exponential function discussed in Figure 4 caption. Lines are fits to the Arrhenius equation, $ln(k_{\text{iobs}})=ln(A)-E_{\text{a}}^{\text{i}}/\mathrm{RT}$, where $E_{\text{a}}^{\text{i}}$ is the apparent activation energy for kinetic phase i (i = 1, 2, or 3) and its value is listed in Table 2.
