The diversity within the RiPP family is staggering, with over 40 known RiPP families, each exhibiting unique structural features and biological functions. Examples include lassopeptides, which are characterized by their highly intertwined, lasso-like structures, and lanthipeptides, known for the presence of lanthionine and methyllanthionine amino acid residues. The length of these peptides can vary significantly, typically ranging from approximately 20 to 110 amino acids.Novel types of RiPP-modifying enzymes This structural variability is a direct consequence of the extensive post-translational modifications (PTMs) they undergo. These modifications can include cyclization, dehydration, glycosylation, prenylation, and the formation of novel cross-links, such as the biaryl C–C, C–N, or C–O linkages found in biarylitides, a newly identified class of ribosomally synthesized and post-translationally modified peptides (RiPPs). The RiPP recognition element (RRE), a specific sequence within the precursor peptide, is essential for recognizing and binding these modifying enzymes, and it is found encoded in about half of all known prokaryotic RiPP classes.

The biosynthesis of RiPPs is a complex and highly regulated process that involves a sophisticated interplay between the precursor peptide and a suite of dedicated enzymes. These RiPP biosynthetic enzymes are the workhorses that install the diverse chemical structures, conferring novel properties and bioactivities upon the peptides. Researchers are actively exploring and engineering these enzymes, recognizing their potential as a valuable biocatalytic toolbox for creating a wide array of modified peptides. Recent advances in the discovery and engineering of RiPPs are continuously expanding our understanding of their biosynthetic logic and unlocking new possibilities for their application.
