In the ERC-StG project STICKY SUGARS, a fully funded 4-year PhD position is available in the Chemical Glycobiology group of Prof. Marthe Walvoort, in the division of Chemical Biology at the Stratingh Institute for Chemistry, University of Groningen. Research in the Walvoort group is dedicated to understanding the structure-activity relation of carbohydrates. One area deals with the investigation of bacterial protein glycosylation to the point where we can start exploiting it to generate novel antibacterial therapies. The other area is dedicated to synthetic method development and production of interesting oligosaccharide structures.
Research project With bacteria increasingly resistant to current antibiotics, new strategies to fight infection are needed. Bacterial adhesin proteins, which play an important role in the establishment of infection, appear to be promising targets for novel therapies. Adhesins enable the first contact between bacteria and host cells. We know that some adhesins are modified with highly unique sugars that are important for adhesin stability and adherence. However, we do not know how widespread this modification is among bacterial strains, and whether it constitutes a good target for antibacterial strategies. A lack of suitable methods for the detection of bacterial adhesin sugars has impeded the detailed study of these sugars, blocking further efforts to develop antibacterial strategies against bacterial adhesin sugars.
The goal of this PhD project is to develop methods to visualize glycosylation directly on adhesin proteins to increase our understanding of adhesin sugars, in terms of timing and prevalence of the modification, which is crucial information to start targeting adhesin sugars. Using enzyme engineering, a set of specific glycosyl transferases will be generated which will be used to develop a specific labelling method for adhesin glycosylation. In addition, labelling methods based on lectins and antibodies will be explored. Subsequently, the novel detection methods will be applied in in vitro (screening) assays on isolated proteins and directly on bacterial cells (lab strains and clinical isolates) under varying conditions. By visualizing adhesin sugars directly on bacteria, we can observe their response to antibacterial treatments and pave the way toward clinical applications in the future.
