Abstract: Artificial metalloenzymes have fed our understanding of how inorganic reactivities emerge, evolve, and diversify in protein environments. Herein, we created dinuclear copper oxidases by genetically encoding a metal-ligating unnatural amino acid (bpy-Ala) per protomer in… read more here.

Abstract: Pyrazolate-based μ-1,2-peroxo dicopper(II) complex 1 undergoes clean 1e- oxidation at low potential (-0.59 V vs Fc/Fc+) to yield the rather stable μ-1,2-superoxo dicopper(II) complex 3, which was characterized by spectroscopic methods (ν̃(O-O) = 1070 cm-1,… read more here.
