Sialic Acid Glycoengineering

Glycoengineering is an important strategy, changing protein-associated carbohydrates to alter the pharmacokinetic properties of proteins. CD BioGlyco has extensive experience in the field of glycoscience and has gained significant experience and expertise in glycoengineering. CD BioGlyco has established several efficient glycoengineering expression systems. Our expression systems provide a novel class of therapeutic glycoproteins with tailored functions. In addition to in vivo glycoengineering in different expression systems, we also perform in vitro glycoengineering of antibodies using a chemoenzymatic approach.

Background

Sialic acids cap the glycans of cell surface glycoproteins and glycolipids. They are involved in a multitude of biological processes and aberrant sialic acid expression is associated with several pathologies. Sialic acids modulate the characteristics and functions of glycoproteins and regulate cell-cell as well as cell-extracellular matrix interactions.

Sialic acid glycoengineering, the introduction of unnatural sialic acids with different chemical properties into sialoglycans, is an approach that is increasingly applied in the field of glycoscience and beyond. Chemically modified analogs of N-acetylmannosamine, the biological precursor of sialic acid, or sialic acid analogs are introduced into the metabolic sialic acid biosynthesis pathway resulting in their incorporation into sialoglycans. With enough biology added to the mix to firmly establish this methodology as a potent new tool for the experimental glycobiologist and pique the interest of the clinician.
