Recent advances in synthetic glycoengineering for biological applications

Carbohydrates are involved in many important biological events such as protein maturation and trafficking, pathogen invasion, immune response, cell-cell communications, and so on. Synthetic and chemoenzymatic approaches for glycoengineering have emerged and been applied in perturbing and modulating the biological processes at the protein or cellular level. In this review, we summarize the recent advances in glycoengineering, including new strategies in chemoenzymatic synthesis of glycans, glycopeptides, glycoproteins, and other glycoconjugates. And, the progresses of cell surface glyco-editing methods for gain of functions are also discussed.
