Chemistry and glycobiology

Area of Science:

• Glycobiology
• Chemical Biology
• Biochemistry

Background:

• Glycobiology research requires sophisticated tools for complex problems.
• Key areas include glycoprotein synthesis, glycan array development, and glycosylation monitoring.

Purpose of the Study:

• To highlight recent advancements in tools and strategies within glycobiology.
• To showcase how these tools facilitate structural and functional studies of glycoproteins and glycans.
• To emphasize the role of these tools in disease monitoring.

Main Methods:

• Glycoprotein synthesis techniques: glycoprotein remodeling, native chemical ligation (NCL), expressed protein ligation (EPL), Staudinger ligation, sugar-assisted ligation, and pathway engineering.
• Glycan synthesis methods: one-pot, chemoenzymatic, and solid-supported syntheses.
• Monitoring post-translational glycosylation using bioorthogonal chemical reporters.

Main Results:

• Development of methods for producing homogeneous glycoproteins with defined glycans.
• Simplification of glycan synthesis for functional and array studies.
• Glycan arrays enable simultaneous testing of numerous carbohydrate-protein interactions with minimal sample.
• Bioorthogonal reporters allow monitoring of glycosylation changes linked to disease progression.

Conclusions:

• Interdisciplinary collaboration between chemistry and biology has driven significant progress in glycobiology.
• New tools and strategies are accelerating research and enabling deeper understanding of complex biological processes involving carbohydrates.
