Der volle Inhalt der QuelleLytic polysaccharide monooxygenases (LPMO) break down polysaccharides and are greatly studied in the context of biomass conversion. They contain a mononuclear copper center which is studied by its magnetic properties. The mechanism of reaction and its intermediates are still unknown. We use a large set of well-known complexes to develop a protocol to predict the magnetic properties of copper systems using computational calculations. This protocol was applied to LPMO models and to an LPMO-inspired tripeptidic complex to elucidate their structural and spectroscopic properties. In addition, we produced a series of complexes to capture potential high-valent reaction intermediates of LPMO. Eventually, the reactivity of one specific complex was studied for its capacity to produce formate in alcohol solvents. Formate was produced at around 120% conversion. Future generations of ligands and complexes were also synthesized and envisioned to understand the reaction pathways of LPMO

Der volle Inhalt der QuelleCopper monooxygenases involved in dioxygen metabolism, are important in numerous living systems. Dopamine β-monooxygenase (DBM) plays a major role in catecholamine biosynthesis, central and peripheral nervous system neurotransmitters. The mechanism of enzymatic action is not totally described, so many structural and functional models have been proposed. The aim of this thesis is to combine two chemistry's domains in order to prepare biomimetic models of DBM. These two domains are supramolecular chemistry, to mimic enzyme-substract complex, and inorganic chemistry, to synthesise analogous active sites. Two models combining a cyclophane-type hydrophobic pocket and a binuclear copper centre have been synthesised. Many intermediate and final products have been totally described (X-ray diffraction, IR, NMR. . . ), informing on conformation, space available, and intra- and intermolecular interactions in these compounds. Moreover an intermediate cyclophane was co-cristallised with a chloroform molecule inside the cavity. One of these binuclear models has been checked in phosphodiesters hydrolysis reaction. Despite an unexpected kinetic curve appearance (tensioactive effect of BNPP may increase active sites availability of complex 18) binuclear complex 18 showed a higher activity (5x) than a mononuclear copper complex (two equivalents). This higher activity can be explained either by hydrophobic interactions increasing the rate of reaction, or synergic effect of the two copper ions (binuclear structure) on hydrolysis

Der volle Inhalt der QuelleLytic polysaccharide monooxygenases (LPMOs) are copper-dependent enzymes involved in the breakdown of recalcitrant polysaccharides, such as cellulose and chitin. The active site copper ion is coordinated by a very unusual coordination motif, consisting of two fully conserved histidines, one of which is located at the N-terminus and binds copper by both its the side chain nitrogen and the free amino terminal group. Such organization, known as “histidine brace” motif allows the oxidative cleavage of glycosidic bonds in recalcitrant polysaccharides, in the presence of dioxygen or hydrogen peroxide and an electron donor. The objectives of the present work have been pursued via an interdisciplinary approach, using tools and fundamental concepts that span from biology to chemistry. The focus was firstly addressed on the natural properties of the active site in the bacterial LPMOs belonging to the AA10 subfamily. Notably, the variability of a second coordination sphere alanine residue (~ 4 Å from the copper ion) was firstly investigated, leading to the discovery of new enzymes with unusual active-site features. The role of active site alanine was then probed by exploring the mutational effect induced by the other occurring residues on both the activity and the physico-chemical properties on the model enzyme SmAA10. Our results emphasize that this unusual coordination motif imparts unique structural and functional features to the copper centre. Furthermore, the SmAA10 active site variants allowed us to create original metal binding sites with the perspective of exploring new abiological metal-based biocatalytic reactions

Der volle Inhalt der QuelleDopamine beta-hydroxylase (DBH) and peptidylglycine alpha-amidating monooxygenase (PAM) are two copper enzymes involved in the activation of molecular oxygen. Among the various approaches developed to understand their mechanism, the study of the structure-activity relashionships by means of crystallography and molecular modeling is a method of choice. The crystallographic structures of complexes models of the active site of DBH, built with ligands of amide type, show that the substrate-like arm is not correctly positionned relativity to the copper. Therefore the hydroxylation of carbons in non-benzylic positions is favored. We also pointed out that the complexes, built on the TEPA ligand, are too sterically constraint to lead to hydroxylated compounds
