Comparison of the survival probability as calculated from Eqs. (15a) and (15b) (full lines) with the transient absorbance changes as determined from experiment (Ref. 4) (symbols). Details of the values assigned to the various parameters in Eqs. (15a) and (15b) are provided in Sec. III. The experimental curves correspond to data from the wild type and five different mutants of Rhodobacter sphaeroides, and reproduce the curves in Fig. 3(A) of Ref. 4. The codes identifying different mutants are explained in Ref. 4.
Comparison of the survival probability as calculated from Eqs. (15a) and (15b) (full lines) with transient absorbance changes as determined from experiment (Ref. 4) (symbols) for a second set of R. sphaeroides mutants. The theoretical curves are constructed with the same parameter values as used in Fig. 1 (see Sec. III for details). The experimental curves reproduce seven of the curves in Fig. S2(A) of the online supporting material of Ref. 4, two of the original curves being omitted for clarity.
Comparison of the function at two different values of the decay constant (full lines) with the function at two different sets of , , and values (dotted lines). In the lower curves (A), is , and , , and are, respectively, 0.45, 0.3, and 0.25. In the upper curves (B), is , and , , and are, 0.25, 0.25, and 0.5, respectively.
Estimates of the parameters and for 15 reaction center mutants of R. sphaeroides as obtained from best fits of [Eqs. (15a) and (15b)] to experimental transient absorbance data (Figs. 1 and 2). is the free energy change relative to the wild type as estimated in Ref. 4. is the corresponding free energy change as calculated from the definition of given after Eq. (7) using the best-fit .
