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 the vicinity of the innate C2 rotational axis of a homo-oligomeric protein. The inherent protein …

The dicopper peroxide product was verified by resonance Raman spectroscopy (v O-O = 880 cm −1). Oxygenation of the same Cu I compound at −90°C in EtCN led to stable generation of the formally transient intermediate. Resonance Raman spectroscopic inquiries later concluded this intermediate as [Cu II (Me 6 tren)(O 2 •−)] +.

The activity of catechol oxidase (CO), the third member of the type-3 class of dicopper proteins, has been less well studied. Initial EXAFS data on CO from Lycopus europaeus revealed a shorter Cu (II)–Cu (II) distance compared with Hc and tyrosinase [5]. In contrast to tyrosinase, CO specificity is limited to o -diphenols, which are converted ...

Four structurally related bis-tridentate N-donor ligands with either two secondary amine or two imine functions were synthesized, and the corresponding dicopper(I) complexes were investigated as catalysts for the tyrosinase-like conversion of 2,4-di-tert-butylphenol (DTBP-H) to 3,5-di-tert-butylquinone (DTBQ).Notably, the imine …

The resulting mono-μ-oxo dicopper(II) complexes catalytically oxygenate a variety of hydrocarbons, establishing an unprecedented, 100 % atom-economic scenario for the monooxygenation of organic substrates from gaseous O 2. Abstract. One of the challenges of catalysis is the transformation of inert C−H bonds to useful products. ...
