The research work presented in this thesis aimed at exploring multidisciplinary and synergistic strategies to develop “programmed” chemo-enzymatic pathways that take advantage of innate substrate promiscuity and computer-aided engineering of α-transglucosylases to produce glycobricks, easy-to-assemble into biologically active molecules mimicking the antigenic polysaccharide moiety – O-antigen (O-Ag) – of the Shigella flexneri lipopolysaccharides. A lightly protected ABC’D’ was first chemically synthesized by our collaborators from the Pasteur Institute. Next, we evaluated the potential of branching sucrases (BRS) from the Glycoside Hydrolase family 70 to glucosylate ABC’D’. They present the advantage of displaying a large promiscuity toward...
