Fig. 6.

Schematic illustration of the atomistic features governing ET in WT azurin. The black curve corresponds to the probability distribution, $P\left(d\right)$, of Ru–Cu distances, $d$, while the green-dashed curve corresponds to the distance-dependent electronic coupling, $H_{\mathrm{A}\mathrm{B}}\left(d\right)$. Reactant basin and dividing surface configurations are indicated in red and blue, respectively.
