Peptide display has enabled identification and optimization of ligands to many targets. These ligands are usually linear or disulfide-containing peptides that are vulnerable to proteolysis or reduction. We report yeast surface and phage display of lanthipeptides, macrocyclic ribosomally synthesized and post-translationally modified peptides (RiPPs). Lanthipeptides contain multiple thioether cross-links that bestow their biological activities. We developed C-terminal yeast display of the class II lanthipeptides lacticin 481 and haloduracin β, and randomization of the C-ring of the former was used to select tight binders to αvβ3 integrin. This represents the first examples of bacterial RiPP production in Saccharomyces cerevisiae for identification of variants with new biological activities. We also report N-terminal phage display of the class I lanthipeptide nisin and randomization of its A- and B-rings to enrich binders to a small molecule, lipid II. The successful display and randomization of both class I and II lanthipeptides demonstrates the versatility and potential of RiPP display.
