Introduction to Peptide Substrates
Peptide substrates are short chains of amino acids that play crucial roles in various biological and biochemical processes. They are widely used in enzyme assays, drug discovery, proteomics research, and diagnostic applications. Enzymes recognize and act on specific peptide substrates, cleaving or modifying them in a highly specific manner. This property makes peptide substrates valuable tools for studying enzyme activity, kinetics, and substrate specificity. In drug discovery, peptide substrates can be used to screen for potential enzyme inhibitors or activators, which may lead to the development of new therapeutic agents. Additionally, in proteomics, peptide substrates are employed to identify and characterize proteases and their substrates, providing insights into cellular signaling pathways and protein processing mechanisms.
