The precise synthesis of proteins and peptides is fundamental for developing innovative therapeutics, high-per- formance molecular probes, and advanced functional materials. Recent advances in single-site selective chemical modification and automated synthesis technologies have significantly improved precision in sequence control, enabled site-specific introduction of functional groups and diversified modification. These developments have effectively addressed the issue of product heterogeneity from traditional non-selective modifications while substantially improving the efficiency and precision of complex sequence synthesis. This review summarizes the research progress in single-site modification strategies for proteins/peptides over the past five years (2020~2025), focusing on site-specific direct modification, ligand-directed modification, and linchpin-directed modification. It also provides a systematic evaluation of recent developments in automated precision synthesis technologies. These technological innovations have not only enhanced the capability for controllable synthesis and precise functionalization of protein/peptide, but also created new opportunities in drug development, molecular probe engineering, and bioconjugation applications. Looking ahead, the development and application of novel bioorthogonal reagents, the integration of innovative dynamic modification technologies, and AI-assisted synthesis route optimization will emerge as key research directions, promising to drive breakthroughs in protein precision synthesis.
