Introduction to Phosphoamino Acid Analogues

Phosphorylation provides a central regulatory mechanism in biological systems. Protein phosphorylation, which acts as a molecular switch regulating protein activity by causing conformational changes in the phosphorylated proteins, is the basis for numerous cellular processes and many pathological conditions. Most of the protein phosphorylation events occur on serine, threonine, and tyrosine residues. Sometimes, phosphorylation also occurs on other amino acid residues, such as histidine, aspartate, and lysine. Although thousands of phosphorylation sites have been identified, their functions remain to be discovered. Therefore, identifying phosphoamino acids in phosphorylated proteins is an important task. Synthetic phosphoamino acids and their analogues have been developed as essential building blocks for the synthesis of biomarcromolecules such as phosphopeptides. They play a diverse and crucial role as active tools in revealing the structural and functional consequences of protein phosphorylation as well as in advancing biomedical research. However, the routine synthesis of phosphoamino acid analogues remains challenging.
