Large protein-like leader peptides engage differently with RiPP halogenases and lanthionine synthetases
2025 / Nature CommunicationsThe biosynthesis of ribosomally synthesized and post-translationally modified peptides (RiPPs) involves binding of the N-terminal leader region of precursor peptides to peptide-modifying enzymes and subsequent modification of the C-terminal core. Canonical RiPP leaders are short and unstructured. However, atypical RiPP leaders called nitrile hydratase-like leader...
