After conducting an analysis of the cryptic cluster region and performing transcriptomic studies, an integrative BAC Vector containing the gene sequence was constructed. The heterologous expression of the cluster in J1074 resulted in the production of the angucyclic product, seongomycin, which allowed for the assesment of its antibacterial, antiproliferative, and antiviral activities. Heterologous production was further confirmed by targeted knock-out experiments involving key regulators of the biosynthetic pathways. We were further able to revise the core structure of maduralactomycin A, using a computational approach.

Bacteriocins are antimicrobial peptides/proteins that can have narrow or broad inhibitory spectra and remarkable potency against clinically relevant pathogens. One such bacteriocin that is extensively used in the food industry and with potential for biotherapeutic application is the post-translationally modified peptide, nisin. Recent studies have shown the impact of nisin on the gastrointestinal microbiome, but relatively little is known of how abundant nisin production is in nature, the breadth of existing variants, and their antimicrobial potency.

Marine-derived enzymes often show distinct physiological properties and great potential for industrial use. Salt ions may improve the stability and expression efficiency of marine enzymes, which requires salt-resistant host based expression platform. Aspergillus oryzae of good protein expression and secretion was evaluated and explored for this purpose.

Focus on 2004 to 2024The rediscovery of natural products (NPs) as a critical source of new therapeutics has been greatly advanced by the development of heterologous expression platforms for biosynthetic gene clusters (BGCs). Among these, species have emerged as the most widely used and versatile chassis for expressing complex BGCs from diverse microbial origins. In this review, we provide a comprehensive analysis of over 450 peer-reviewed studies published between 2004 and 2024 that describe the heterologous expression of BGCs in hosts.

Although floral morphology in ornamental chrysanthemums has been widely investigated, its genetic basis in medicinal varieties such as Chrysanthemum morifolium cv. 'Hangju' remains largely unexplored, despite its direct relevance to both capitulum development and medicinal quality. To address this gap, we performed transcriptome profiling of ray and disc florets from wild-type and mutant plants, which led to the identification of two MYB-related transcription factor genes, CmDIV-like and CmRAD1, as differentially expressed and potentially associated with altered floral symmetry.

We previously demonstrated the CFTR correctors VX-445 (elexacaftor) and S-VX-121 (vanzacaftor) potentiate heterologously-expressed BK channels, as well as in primary human bronchial epithelial cells (HBEs). This potentiation of BK resulted in altered vasoreactivity and neuronal excitability. We postulated novel compounds could be identified that would potentiate BK while not affecting CFTR.
