Despite being confined to twenty proteinogenic amino acid building blocks, the structural complexity and diversity of RiPPs that arise from enzymatic posttranslational modifications (PTMs) surpass expectations and are now believed to be comparable to those produced by non-ribosomal peptide synthetases. Here, we highlight the PTM enzymes characterized over the past decade that engage the -(NH-Cα-CO)n- repeating units in transformations, particularly those leading to structural rearrangements by peptide backbone remodeling. Unveiling the catalytic mechanisms of these unusual PTM enzymes deepens the understanding in RiPP biosynthesis and, eventually, will enhance our capability of rational design, development and production of functional peptide agents using synthetic biology strategies.","PeriodicalId":94,"journal":{"name":"Natural Product Reports","volume":" ","pages":""},"PeriodicalIF":10.2,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144109175","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}

However, many microbial species also employ unusual redox cofactors such as the coenzyme F420 or the peptide-derived pyrroloquinoline quinone (PQQ). In this review, we introduce the reader to the recently discovered bacterial redox cofactor mycofactocin (MFT), a valine-tyrosine-derived small molecule of the class of ribosomally synthesized and post-translationally modified peptides (RiPPs) with remarkable biosynthetic and functional similarities to PQQ. The cofactor plays an important role in the reoxidation of non-exchangeable nicotinamide redox cofactors of specialized oxidoreductases in mycobacteria and related actinobacteria. We highlight the bioinformatic discovery of the mycofactocin gene cluster and its auxiliary genes, present strategies for the chemical synthesis of the cofactor, and take a detailed look at the biosynthesis of the glycosylated molecule. Subsequently, the diverse mycofactocin-inducing conditions and associated oxidoreductase families are reviewed, and a potential electron transfer route from high-energy alcohols via mycofactocin to oxygen as a final electron acceptor is presented. The review concludes with a comparison of the physiological roles of PQQ and MFT, and an outlook for future research questions and potential biotechnological applications of mycofactocin.","PeriodicalId":94,"journal":{"name":"Natural Product Reports","volume":" ","pages":""},"PeriodicalIF":10.2,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144075115","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}

However, two key gaps left by the Nagoya Protocol are being addressed, introducing new obligations for marine natural product scientists: under the auspices of the Convention on Biological Diversity (CBD), a compromise agreement was reached in November 2024 that regulates the use of Digital Sequence Information (DSI) on Genetic Resources. Within the next few years, the 2023 Biodiversity Beyond National Jurisdiction (BBNJ) Agreement is expected to take effect. This treaty covers the access to and use of marine biodiversity of areas beyond national jurisdiction for research and development. In a time when genetic research and marine biodiversity are key to scientific advancement, these evolving policies affect how genetic information is stored, shared, and used, raising emerging questions for the scientific community about their direct impact and the complexities of compliance. Despite continuous developments and scientific community involvement, there remains a notable gap in communication between policy changes and their accessible dissemination to researchers. Addressing this gap is crucial for the continuation of research and the effective use of relevant resources. The main goal of this viewpoint article is to provide a concise guide to recent policy developments relevant to natural product researchers that should be incorporated and harmonized into ongoing scientific activities.","PeriodicalId":94,"journal":{"name":"Natural Product Reports","volume":" ","pages":""},"PeriodicalIF":10.2,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143956609","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}

Advances in genome sequencing and computational tools have revealed a wealth of cyanobacterial biosynthetic gene clusters (BGCs). However, progress in genome-driven discovery has been hindered by challenges in manipulating native hosts and the limited availability of efficient heterologous expression platforms. This highlight focuses on recent synthetic biology innovations on cyanobacterial systems that address these obstacles, facilitating the production of diverse cyanobacterial natural product families. We discuss key features of widely used cyanobacterial chassis, such as Synechocystis sp. PCC 6803, Synechococcus elongatus UTEX 2973, Anabaena sp. PCC 7120, and emerging hosts. Advances in BGC cloning, combinatorial biosynthesis, transcriptional and translational regulation, and host engineering are also highlighted.

Within the UPS, target proteins are polyubiquitinated through sequential reactions catalyzed by ubiquitination-related enzymes. These ubiquitinated proteins are then recognized and degraded by the 26S proteasome. Deubiquitinating enzymes cleave the formed polyubiquitin chains and regulate protein degradation, thereby contributing to precise regulation of the system. Dysregulation of the UPS is associated with cancer, immune disorders, and neurodegenerative diseases, making it a potential target for drug discovery. To date, a variety of natural products that target the UPS have been discovered and used in pharmaceutical development, and these compounds have provided important insights into the molecular mechanisms of UPS regulation. This review describes natural products that inhibit protein degradation in the UPS and activate protein degradation mediated by the 20S proteasome, thus clarifying their mechanisms of action and exploring their potential applications as therapeutic agents.","PeriodicalId":94,"journal":{"name":"Natural Product Reports","volume":" ","pages":""},"PeriodicalIF":10.2,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143958516","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}
