  "account": "The benzoxazolinate moiety, a crucial functional group, is found in select natural products (NPs) with a range of bioactivities, such as antitumor, antibacterial, and cytotoxic effects. However, only a limited number of bacterial strains and NPs have been reported to harbor this uncommon bis-heterocyclic moiety, indicating a largely unexplored chemical space. Recently, a large-scale genome mining approach was employed to identify 277 potential biosynthetic gene clusters (BGCs) across various bacterial hosts, including some previously unreported genera and strains. These BGCs were categorized into three distinct compound classes: benzoxazolinate, benzobactin, and ashimides, based on sequence similarity network clustering. Predictive bioactivity analysis of the discovered BGCs highlighted their antibacterial and cytotoxic potential, suggesting they could be valuable for future experimental validation and functional studies. Additionally, a neural network-based bioprospecting model was presented, demonstrating its effectiveness in identifying rare BGCs encoding benzoxazolinate-containing molecules from genomic sequences. In summary, this research broadens the known range of bacterial hosts capable of producing benzoxazolinate-containing NPs and offers a comprehensive framework for the discovery and identification of candidate BGCs.",
