Structural Enzymology and Carbohydrate Chemistry

Research Summary

My research spans the disciplines of Chemistry and Biology, with a focus on the structural enzymology and chemical biology of proteins involved in the synthesis and degradation of carbohydrates.  Current projects include:

  • the enzyme discovery and the enzymology of biomass conversion, focusing on the human intestinal microbiota and on fungal and bacterial lytic polysaccharide monooxygenases;
  • the O-GlcNAc modification and its role in neurodegeneration;
  • glycan synthesis and degradation in health and disease, probing cancer viral invasion and lysosomal storage diseases;
  • opiate biosynthesis.

Gideon Davies received his PhD from the University of Bristol in 1990, and went on to postdoctoral research at EMBL Hamburg and CNRS Grenoble. In 1996 he received a Royal Society University Research Fellowship to work on Carbohydrate-Active Enzymes. He was made a Professor of the University of York in 2001.  He has won many awards including the 2015 Davy Medal of the Royal Society, the 2014 Khorana Prize of the Royal Society of Chemistry, and the 2010 Gabor Medal of the Royal Society. Gideon was elected a a Fellow of The Royal Society in 2010, and as a member of the European Molecular Biology Organization the same year.  He was also elected a Fellow of the Academy of Medical Sciences in 2014.
