Spin-driven activation of dioxygen in various metalloenzymes and their inspired models

Reaction Mechanisms of Metalloenzymes and Synthetic Model Complexes Activating Dioxygen Reaction Mechanisms of Metalloenzymes and Synthetic Model Complexes Activating Dioxygen

Electronic structure contributions to function in bioinorganic chemistry.

Many metalloenzymes exhibit distinctive spectral features that are now becoming well understood. These reflect active site electronic structures that can make significant contributions to catalysis. Copper proteins provide well-characterized examples in which the unusual electronic structures of their active sites contribute to rapid, long-range electron transfer reactivity, oxygen binding and ...

Preface to Volume 15 Sustaining Life on Planet Earth: Metalloenzymes Mastering Dioxygen and Other Chewy Gases

In this volume of the Metal Ions in Life Sciences series the mastering of dioxygen (O2), methane (CH4), and ammonia (NH3) by mainly manganese-, ironand copper-dependent metalloenzymes and their biomimetic complexes is discussed. It is closely related to Volume 14, The Metal-Driven Biogeochemistry of Gaseous Compounds in the Environment, which deals with the biogeochemistry of gases including di...

Synthesis, Characterization, and Reactivity of Cobalt ACHTUNGTRENNUNG(III)–Oxygen Complexes Bearing a Macrocyclic N-Tetramethylated Cyclam Ligand

Oxygen-coordinating metal species, such as metal–peroxo, –hydroperoxo, and –oxo complexes (Scheme 1), have been frequently invoked as reactive intermediates in the catalytic cycles of dioxygen activation by metalloenzymes, such as heme and nonheme iron monooxygenases and copper-containing enzymes. In biomimetic studies, synthetic analogues of these active oxygen intermediates have been intensiv...

Mononuclear Manganese–Peroxo and Bis ACHTUNGTRENNUNG(m-oxo)dimanganese Complexes Bearing a Common N-Methylated Macrocyclic Ligand

Metal–oxygen adducts (Mx Ox, x=1 or 2), such as metal– superoxo, –peroxo, and –oxo species, are key intermediates often detected in the catalytic cycles of dioxygen activation by metalloenzymes. In biomimetic and synthetic chemistry, numerous Mx Ox complexes have been prepared and characterized with various physicochemical methods as structural and functional models of enzymes. Among the Mx O2 ...
