AI-Driven Insights into Lasso Peptide Biosynthesis

Lasso peptides are natural products made by bacteria. Their unusual lasso shape endows them with remarkable stability, protecting them from extreme conditions. In a new study, published in Nature Chemical Biology, researchers have constructed and tested models for how these peptides are made and demonstrated how this information might be used to advance lasso peptide-based drugs into the clinic.
