Figure 3: The derived reaction times, various quantum yields and electron-transfer reorganization energies involved in DNA repair by photolyase.
From: The molecular origin of high DNA-repair efficiency by photolyase
(a) The reaction times for five elementary reactions involved in repair. LT=deactivation lifetime; FET=forward electron transfer; BET=back electron transfer; SP2=the second C6-C6′ splitting; ER=electron return after repair. The first C5-C5′ splitting is ultrafast for all mutants within 10 ps and not shown here. The dashed lines link two sets of two competition channels responsible for the repair efficiency. Also shown are the corresponding quantum yields of ΦFET and ΦSP2 for the two sets of competitions and the resulting total quantum yield of ΦT (ΦFET × ΦSP2). (b) Two-dimensional (2D) contour plot of the electron-transfer dynamics relative to free energy (ΔG0) and reorganization energy (λ) for FET (filled circle), BET (open square) and ER (open diamond) obtained in this study. The former two are in the ET normal region and the latter one is in the Marcus inverted region.
