Solid-phase peptide synthesis (SPPS) is a cornerstone technique for constructing peptides, and its integration with enzymatic catalysis, particularly using subtilisin, offers a powerful and often milder alternative to traditional chemical methodsPeptiligase, an enzyme for efficient chemo-enzymatic .... This approach leverages the specificity of enzymes to form peptide bonds, enabling the synthesis of complex peptide sequences, including those with unique structural features or modifications. While subtilin itself is a peptide, the search term "solid-phase peptide synthesis subtilin" points to the use of enzymes like subtilisin in the context of solid-phase methods, rather than the synthesis of subtilin itself via SPPS.作者：TJ Tolbert·2004·被引用次数：9—A 12-residue peptide ester is synthesized bysolid-phase peptide synthesisusing a PAM-modified Rink amide resin that allows the formation of a peptide es …

The Power of Subtilisin in Peptide Synthesis

Subtilisin, a serine protease, has emerged as a versatile catalyst for peptide bond formation. Its ability to function in organic solvents and under mild conditions makes it an attractive option for SPPS.
