Figure 1.

A: Structure of Re126WWCuII (PDB: 6MJS, chain A) showing intramolecular distances between the redox cofactors. B: The interfacial region between chains A and D in the asymmetric unit of Re126WWCuII, showing distances relevant to intermolecular ET. The four interfacial tryptophans form a “cage” with indole groups separated by less than 4 Å. C: The interfacial region between chains A and C in the asymmetric unit of Re126FWCuII, showing distances relevant to intermolecular ET. D: The interfacial region of Re126WFCuII showing distances relevant to intermolecular ET. A Pymol-generated symmetry match to the molecules in the asymmetric unit is shown. (More structures, including Re126TWCuII and ReW122CuII, are shown in Figure S1.)
