OFFER DESCRIPTION

Exploration ofaldolases substrate specificity for applications in organic synthesis

In the field of green chemistry, isolated enzymes are well-established as useful tools for the development of new processes in organic synthesis. Biocatalysts facilitate the stereo-, regio-and enantioselectively production of a large variety of organic compounds in exceptionally soft and mild conditions. The discovery and study of new enzymes with amazing properties, is an international major aim in order to widenthe chemist’s toolboxfor applications insustainable organic synthesis.Our research group is particularly focused on aldolases, enzymes catalyzing stereoselectivelyC-C bond formation. The main objective of this project is to explore new aldolases, isolated from the biodiversity, and discovered by high throughput screening.This innovating multi-disciplinary project, at the interface of chemistry and biology,is part of apartnership established several years ago with the CEA-Génoscope(Evry).These biocatalysts will bescreened for originalcatalytic activities, never described before,as exemplifiedin the scheme below. Our experience has already been illustrated by the publication of the screening of several aldolase families with different properties.By structure modulation of the electrophilesand nucleophiles, theirsubstrate specificity will be fully studied, for the best hits, in the preparation of attractive aldols as such or as synthons of more complex molecules of biological interest. Their stereochemistry will be determined by running small scale syntheses. This substrate specificity study will be extended to enzymes from our library, for the research of new and particularly original reactions.

Skills targeted :

Biocatalysis (enzyme productionand purification, mutant construction (error-prone PCRor semi-rational approach) enzymatic reaction implementation), analysis (HPLC, UV spectroscopy), classical organic synthesis and purifications (silica gel or ion exchange chromatography), NMR, Mass spectrometry analysis.

No pre-requisite in biocatalysis and/or in enzymology is required.
