Silencing prion: Copper-catalyzed transformations of prion protein (PrP) lead to the production of reactive oxygen species (ROS), PrP oxidation, and cleavage and aggregation in transmissible spongiphorm encephalopathies. Zn(7) MT-3 efficiently targets Cu(II) bound in different coordination modes to PrP-Cu(II) . By an unusual redox-dependent metal-swap reaction, MT-3 modulates the catalytic redox properties of PrP-Cu(II) .
