Abstract:
The catalytic redox activity of Cu(II) bound to the motif NH2–Xxx-Zzz-His (ATCUN) with ascorbate and H2O2/O2 is very low and can be stopped via Cu(I)-chelation. This impacts its application as an artificial Cu–enzyme to degrade biomolecules via production of reactive oxygen species in a Cu(I)-chelator rich environment like the cytosol.
