The role of tryptophan: Protein microsurroundings with a strong Lewis acidity inhibit electron-hole transport through the indole side chains of tryptophan (Trp) residues in proteins, while systems with a strong Lewis basicity strongly enhance the electron-relay ability of Trp residues, so that ET can be switched off and on, respectively (see picture).
