Researchers at the University of Utah found an enzyme called PapB that can link ends of therapeutic peptides into tight rings. This makes medicines like Ozempic more durable and effective.

Scientists have discovered a new way to improve how diabetes medications work in the body. Researchers at the University of Utah identified an enzyme called PapB that can reshape therapeutic peptides, which are protein-like drugs used to treat diabetes and obesity. These peptides are often linked together into rings, known as macrocyclization, to create compact structures that perform better in the body. The discovery could be especially useful for enhancing GLP-1 medications like semaglutide, the active ingredient in Ozempic and Wegovy.

Ring-shaped peptides offer several advantages over their open-chain counterparts. They are more stable, remain active longer, and can better interact with biological targets. This is because ring-shaped structures are less prone to degradation or breakdown, making them more effective at treating diseases.

The team tested PapB on three different GLP-1-like peptides and found that the enzyme successfully converted linear molecules into ring-shaped versions. These results indicate that PapB could function as a flexible, plug-and-play tool for modifying peptides even at late stages of drug development.
