Régis Faure


CNRS senior research scientist

Actual position and research subject

My research interests focus on biomolecular engineering, combining chemical synthesis and protein engineering approaches, to design evolved and/or artificial enzymatic catalysts for glycosylation (enzyme catalysis, bioorganic chemistry & biomolecular engineering).

After a first degree in Physical Chemistry (University of Toulouse, 1998) and a PhD in Biological Chemistry (University of Grenoble, 2004), in the field of chemo-enzymatic glycosynthesis, I spent almost two years as a postdoctoral fellow in the field of glycochemistry in the Department of Chemistry at UQAM. Since joining the CNRS as a tenured researcher in TBI (2007), I pursued the development of my skills in organic synthesis, while acquiring new knowledge and practical knowhow in the fields of protein biochemistry, enzyme engineering and high-throughput screening. I supply vital in-house expertise in the field of (glyco)chemistry, supporting research focused on enzyme discovery through the design of ad hoc substrates for easy specific detection of enzymatic activities. I also provide strong input in the area of enzymatic (glyco)synthesis, using carbohydrate active enzymes (transglycosylases from evolved glycoside hydrolases, esterases, etc.) and work on development of novel enzymes for de novo synthesis of carbohydrates. Most recently, I have shifted a part of my research activity towards the redesign of enzyme active sites, also targeting protein glycosylation as an applied aim. This research calls upon my knowledge of chemistry and uses non-canonical amino acids to extend the chemical functionalities of naturally occurring enzymes.
