Applications of Peptide Sequencing in Biomedicine, Agriculture, and Biotechnology
Peptides, as essential functional molecules in biological systems, play critical roles in signal transduction, immune response, enzymatic regulation, and other vital processes. The rapid advancement of peptide sequencing technologies, particularly in biomedicine, agriculture, and biotechnology, is accelerating the transition from molecular-level investigations to practical applications across these industries.
Technical Background and Principles of Peptide Sequencing
Peptide sequencing refers to the determination of amino acid sequences within peptide fragments. Currently, mainstream approaches include tandem mass spectrometry (MS/MS) and Edman degradation, with high-resolution mass spectrometry emerging as a central tool in the field. By fragmenting peptide chains and integrating results with database matching, deconvolution algorithms, and bioinformatics tools, researchers can achieve rapid and precise sequencing of peptides in complex samples. This technique not only provides insights into protein structures and post-translational modifications but also forms the molecular foundation for functional characterization.
Biomedical Applications and Value
1. Disease Mechanism Elucidation and Biomarker Discovery
In biomedicine, peptide sequencing offers molecular-level insights into disease mechanisms. Comprehensive profiling of peptidomes from body fluids and tissues enables the identification of disease-associated peptides and their modification patterns, supporting early diagnosis, prognosis evaluation, and therapeutic target identification. Furthermore, peptide sequencing accelerates the discovery of novel biomarkers by facilitating the identification of bioactive peptides such as antibody epitopes, cytokines, and hormones.
2. Precision Medicine and Personalized Therapies
Peptide sequencing enables characterization of patient-specific peptidomes and their modification states, providing a molecular basis for personalized diagnostic and therapeutic strategies. Sequencing of immune-related peptides allows researchers to assess immune system functionality, thereby advancing the precision development of vaccines, immunotherapies, and individualized drug selection.
Agricultural Applications and Potential
1. Plant Resistance and Developmental Regulation
Peptides are key regulators of plant growth, development, and stress responses. Through peptide sequencing, functional peptides involved in plant immunity, stress adaptation, and developmental processes can be identified, serving as molecular targets for crop improvement. Additionally, sequencing reveals the diversity and regulatory networks of signaling peptides in plants, laying the groundwork for breeding high-efficiency, stress-tolerant cultivars.
2. Animal Health and Enhanced Productivity
In livestock production, peptide sequencing provides foundational data for the development of vaccines, immune enhancers, and nutritional supplements. By analyzing bioactive peptides and their functions in animals, researchers can formulate targeted feed additives to enhance health and productivity. Peptide sequencing also plays an important role in animal disease diagnostics and treatment strategy optimization.
Innovative Applications in Biotechnology
