Introduction to Peptide Substrates
Peptide substrates are short chains of amino acids that serve as essential tools in various biological and biochemical research, as well as in the development of pharmaceuticals, diagnostics, and biotechnology products. They are widely used in enzyme activity assays, where they act as the target molecules for enzymes. When an enzyme interacts with a peptide substrate, it catalyzes a specific chemical reaction, leading to a detectable change such as a color change or the release of a fluorescent signal. This property makes peptide substrates invaluable for studying enzyme kinetics, screening for enzyme inhibitors or activators, and diagnosing diseases based on abnormal enzyme activities.
In addition to enzyme assays, peptide substrates are also used in cell signaling research, as they can mimic the natural ligands of cell - surface receptors. By using peptide substrates, researchers can better understand how cells communicate with each other and how these signaling pathways are disrupted in diseases. Moreover, in the field of drug discovery, peptide substrates can be used to evaluate the efficacy and safety of new drug candidates.
