FIG. 3.

Schematic representation of PCET dynamics in [HG3W + Ag]+ metalpeptide complexes. Irradiation at 266 nm initiates an electron transfer from tryptophan to Ag+, leading to the loss of Ag. Electron transfer is followed by proton transfer from tryptophan to histidine with formation of a distonic ion. The peptide structures are schemes and do not correspond to calculated structures.
