Carbohydrates add a level of diversity across all forms of life that is unparalleled by the information content of nucleic acids and proteins. The lack of a simple template to translate aglycan code into defined sugar structures contributes to this complexity and provides a challenge for efforts aimed at the production of biologically important glycans and glycoconjugates. With the discovery of glycoprotein synthesis in bacteria and functional transfer of glycosylation pathways between species, Escherichia coli cells have become a tractable host for understanding glycosylation and the underlying glycan code of living cells. Moreover, efforts to manipulate the pathways from sugar nucleotides to glycolipids to glycoproteins have transformed E. coli into a living factory for scalable, bottom-up production of complex glycoconjugates by design. Here, I will discuss our efforts to develop E. coli for the biosynthesis of a diverse array of glycan structures, which can be used to tailor the activity, stability, half-life, and immunogenicity of a given biopharmaceutical. I will also discuss our efforts to unify protein glycosylation in E. coli with the advanced tools of protein engineering such as cell surface and phage display technologies. The result is a powerful new way to engineer the enzymes, pathways, end-products, and genomes of glycoengineered bacteria for creating the next generation of protein therapeutics and vaccines for a wide range of human diseases.

 

Matthew P. DeLisa is the William L. Lewis Professor of Engineering in the School of Chemical and Biomolecular Engineering at Cornell University. His research focuses on understanding and controlling the molecular mechanisms underlying protein biogenesis – folding and assembly, membrane translocation and post-translational modifications – in the complex environment of a living cell. Professor DeLisa received a B.S. in Chemical Engineering from the University of Connecticut in 1996; a Ph.D. in Chemical Engineering from the University of Maryland in 2001; and did postdoctoral work at the University of Texas-Austin, Department of Chemical Engineering. DeLisa joined the Department of Chemical and Biomolecular Engineering at Cornell University in 2003. He has also served as a Gastprofessur at the Swiss Federal Institute of Technology (ETH Zürich) in the Institut für Mikrobiologie.
