Synthesizing peptides with post-translational modifications (PTMs) such as phosphorylation and glycosylation enables the study of these critical regulatory mechanisms. PTMs play essential roles in protein function, and modified peptides are powerful tools for studying signaling pathways, enzyme activity, and protein-protein interactions.
Phosphorylation is one of the most common and important PTMs, regulating protein activity, localization, and interactions. Phosphopeptides—peptides containing phosphorylated serine, threonine, or tyrosine residues—are essential for studying kinase activity, phosphatase function, and signaling pathways. The modified peptide synthesis service market is expected to grow at a CAGR of 5.7% from 2025 to 2031[reference:108].
Glycosylation involves the attachment of sugar molecules to proteins, affecting folding, stability, and function. Glycopeptides—peptides containing glycosylated residues—are used to study glycan function, develop vaccines, and investigate disease mechanisms. The synthesis of glycopeptides is technically challenging due to the complexity of glycan structures, but recent advances have made these molecules more accessible.
Other PTMs that can be incorporated into synthetic peptides include acetylation, methylation, ubiquitination, and lipidation. Each modification provides insights into specific regulatory mechanisms and can be used to develop tools for studying protein function.
