Introduction of Phosphorylation Modification

Phosphorylation is one of the most extensively and diligently studied post-translational modification (PTM) which orchestrates a variety of cellular functions like cell growth, differentiation, and apoptosis. Protein kinases and phosphates are the enzymes that phosphorylate and dephosphorylate the proteins, respectively. These enzymes work in a balanced state to regulate the function of proteins. Phosphorylation imparts conformational changes in the protein thereby modify its affinity for another protein, activates or deactivates an enzyme protein, or facilitates its degradation by the ubiquitin-proteasome complex.

Phosphorylation Modification of Polysaccharides

The hydroxyl groups on the polysaccharides are replaced by a phosphate group, known as phosphorylation of polysaccharides. Phosphoric acid and its anhydride, phosphorus pentoxide (P2O5), phosphorus oxychloride (POCl3), phosphate are commonly used for the phosphorylation of polysaccharides. The introduction of the phosphate group will increase the immunosuppressive activity of polysaccharides. This advantage makes polysaccharide phosphorylation have great significance. It showed that dextran phosphorylation could significantly promote mouse spleen lymphocyte mitosis, enhance the expression of B lymphocytes and dendritic cells on the surface of CD86 and CD69, but also could promote IL-10 secretion. The immunomodulatory activity of phosphorylated polysaccharides was related to the absorption of calcium ions.
