# Navigating the Complexities of Full-length Lanthipeptide Synthesis Solid Phase
Exploring the intricate world of bioactive structures often leads researchers to the fascinating class of ribosomally synthesized and post-translationally modified peptides, or RiPPs. Among these, the full-length lanthipeptide synthesis solid phase methodology stands out as a critical area for those of us deeply invested in peptide engineering and chemical biology.
The primary challenge in working with lanthipe Oct 26, 2023 · Here, we describe for the first time a novel lanthipeptide, inecin L, a bacteriocin from Lactobacillus iners with … ptides lies in their unique macrocyclic topology. Unlike linear chains, these molecules are characterized by intramolecular thioether linkages known as lanthionines or methyllanthionines. Achieving this structure through chemical means requires precise control over amino acid residues, particularly the dehydration of serine and threonine.
In my experience, the synthetase of lanthipeptides typically governs the natural maturation process. However, when recreating these patterns in a laboratory setting via solid-phase peptide synthesis (SPPS), we must mimic these enzymatic events. The lanthipeptide macrocyclic constraint provides the stability necessary for various functional investigations, making the synthesis protocol a highly technical endeavor.
