When we discuss chemoenzymatic peptide synthesis (or chemo-enzymatic peptide synthesis), we are referring to the hydrolase-catalyzed, stereoselective formation of peptide bonds. Unlike conventional chemical routes that often rely on harsh, environmentally taxing reagents, this approach is remarkably mild.
In these systems, amino acids acting as acyl donor and nucleophile are recognized by the S subsite and S' region of the enzyme. By leveraging proteolytic enzymes as effective catalysts, researchers can achieve highly specific bond formation. The process is often categorized into equilibrium and kinetically controlled enzymatic peptide synthesis, each offering distinct advantages depending on the target sequence length and complexity.
Why Enzymes are Revolutionizing the Workflow
The primary appeal of enzymatic peptide synthesis lies in its precision. Peptide ligases, which are enzymes that form peptide bonds (amide bonds), act as powerful tools for coupling segments, which is particularly beneficial for long-chain peptides.

Furthermore, the industry is increasingly adopting chemo-enzymatic peptide synthesis (CEPS) because it significantly reduces the chemica Enzymatic synthesis of peptide therapeutics l waste associated with standard solid-phase protocols. For instance, an efficient enzymatic method for producing oligopeptides from unprotected amino acids has shown that biocatalysis can maintain high yields while simplifying purification steps.
Technical Considerations and Applications
To understand the scope, it is helpful to look at how both chemical and enzymatic peptide synthesis methods are summarised in current literature. While chemical synthesis remains a mature technology, it is often plagued by a lack of specificity. In contrast, enzymatic approaches—including peptide synthesis mediated by thiolsubtilisin using peptide thioester as building block—allow for more refined control.
Some specialized processes even involve modular enzymes frequently used to synthesize small peptides, such as non-ribosomal peptide synthetases (NRPSs). In certain laboratory settings, the ability to synthesize peptides in organic solvents using enzymes like thermolysin has opened doors to creating complex structures that were previously difficult to access.
Personal Perspective on Biocatalysis
From my experience observing these developments, the transition toward recent applications of enzyme catalysis in peptide synthesis is driven by the need for greener, more reliable production. Whether the goal is the creation of small molecules designed to make peptides and small proteins of biological and pharmaceutical interest, or the assembly of specialized sequences, the integration of enzymes is undeniable.
