Despite their structural complexity, RiPPs are encoded by relatively small biosynthesis gene clusters. RiPP maturase enzymes are diverse and often promiscuous, offering significant biotechnological potential. However, their lack of conserved features makes genome-based discovery of novel RiPPs challenging. Recent advances in biosynthetic understanding and genome mining techniques have led to the identification of numerous uncharacterized RiPP biosynthetic gene clusters, often flanked by genes encoding non-RiPP moieties, in microbial genomes. Leveraging this information, a new class of natural products, hybrids of RiPPs and non-RiPP elements, has recently been discovered. Among them, RiPPs bearing fatty acyl groups, referred to as RiPP-derived lipopeptides, represent a newly emerging class of lipopeptide natural products with significant antimicrobial activity.</p>","PeriodicalId":94,"journal":{"name":"Natural Product Reports","volume":" ","pages":""},"PeriodicalIF":10.2,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144641286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among these, specialized small molecules referred to as natural products (NPs) play an important role in microbe-drug/environment interactions, microbe-microbe, and microbe-host interactions. Microbial communication using NPs allows microbes to sense quorum, form biofilms, eliminate competition, establish symbiosis, evade immune attack, and respond to stress.
