The leader peptide plays a crucial role in guiding the core peptide through the maturation process, often acting as a recognition element for specific modifying enzymes. The core peptide houses the sequence that will be extensively altered through post-translational modifications (PTMs), resulting in the final bioactive molecule. As highlighted in various studies, an emerging theme in RiPP biosynthesis is the critical role of the leader peptide or follower peptide in stabilizing the active conformations of the enzymes responsible for these modifications. Even the RiPP precursor recognition element (RRE), a conserved domain found in many prokaryotic RiPPs, underscores the intricate molecular recognition involved in this pathway.
