At its core, peptide synthesis is the process of chemically or biologically creating peptides by joining amino acids together in a specific sequence. This intricate process is facilitated by enzymes known as peptide synthetases. These enzymes are a related group, characterized by their ability to bind, activate, and modify the amino acid substrates. They are often described as large, multifunctional enzymatic complexesStructural Biology of Non-Ribosomal Peptide Synthetases - PMC.
