Thématiques

My research interests are in the area of biochemistry at the interface between biological, catalytic and inorganic chemistry. With my group we are interested in studying metalloenzymes, in particular copper containing oxidases, that we functionalize with different nano-objects (e. g. transition metal complexes) to obtain hybrid catalysts with original properties. We are currently developing researches on the following topics: 1) bioinspired photo-oxidases allowing a renewable Oxygen Atom Tranfer Reaction, 2) original hybrid Pd-based oxygenases as novel catalysts for environmentally friendly industrial processes, 3) surface-ordered enzyme for high performance bio-cathodes, and 4) surface-modified enzymes with an efficient control of the selectivity.

 

Catalysts based on surface functionalized laccases

with Yasmina Mekmouche, Viviane Robert, Pierre Rousselot Pailley, Jalila Simaan

 

Laccases are well known biocatalysts with great robustness, high oxidation power and substrate versatility.[1] Their unique set of copper centres - a near-surface located mononuclear type 1 and an embedded tri-nuclear cluster (TNC) made of a type 2 and a binuclear type 3 - couple the oxidation of substrates (organic or metal ions) to dioxygen reduction.[2] We shape new catalysts based on oriented functionalizations of a laccase surface with different “plug-ins”.
 From our initial demonstrations on bi-molecular systems - a sensitizer/laccase system coupling the light driven four-electron reduction of dioxygen to water[3] to the photo-oxidation of styrene[4] or a Pd(II)/ laccase system competent for the aerobic oxidation of alcohol in mild conditions[5] -  our latest architectures are based on the oriented grafting of the enzyme surface with prospects on olefin oxidation[6] and laccase functionalized electrode materials[7].
