BIORESOUR BIOPROCESS 2025; 12:35. [PMID: 40246774 PMCID: PMC12006653 DOI: 10.1186/s40643-025-00864-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2024] [Accepted: 03/14/2025] [Indexed: 04/19/2025] Open
Abstract
To explore the chemical and biological diversities of diterpenoids from the fungus Talaromyces adpressus, a previously unknown biosynthetic gene cluster (BGC, tdn) for sordarin (a well-known fungal antibiotics) was discovered by leveraging the genome mining method. Heterologous expressions of key genes of tdn in Aspergillus oryzae, led to the determination of one new diterpenoid, cycloaraneosene-9-ol-8-one (4), and three known diterpenoids, cycloaraneosene (1), cycloaraneosene-9-ol (2), cycloaraneosene-8,9-diol (3). The structures of 1-4 was elucidated well via detailed analysis of 1D and 2D NMR, GCMS, HRESIMS, IR data, and comparison with reported data. Structurally, compounds 1-4 were belonging to fusicoccane diterpenoids with a classical tricyclic 5/8/5 ring system, which are participated in the biosynthesis of sordarin. Compound 4 maybe a key precursor for a Baeyer-Villiger like reaction with C8-C9 bond cleavage in the biosynthetic pathway of sordarin. Moreover, all isolates were evaluated for their bioactivities, compounds 3, and 4 exhibited inhibitory activities against the human cancer cell lines with IC50 values ranging from 7.8 to 32.4 µM. 3 and 4 promote cell apoptosis of HCT-116 and HepG2 cells, and suppress cell migration of HepG2 cells. As well, 3 and 4 also decrease gene expression of cell proliferation related molecules BCL-2 and cyclin D1, while increase expression of cell apoptosis related gene BAX. Targets predication and molecular docking indicate that compound 4 exhibits stronger affinity for DBL, suggesting its excellent binding potential. This finding will be enriched the structures and bioactivities of diterpenoids with a tricyclic 5/8/5 ring system, most importantly, will provide new strategies for the synthetic biological research of sordarins.

Tang X, Zhang XJ, Pan JF, Guo K, Tan CL, Zhang QZ, Long LP, Ding RF, Niu XM, Liu Y, Li SH. Z/E configuration controlled by a Taxus sesquiterpene synthase facilitating the biosynthesis of (3Z,6E)-α-farnesene. PHYTOCHEMISTRY 2025; 229:114304. [PMID: 39424093 DOI: 10.1016/j.phytochem.2024.114304] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/05/2024] [Revised: 09/28/2024] [Accepted: 10/15/2024] [Indexed: 10/21/2024]
Abstract
Plant enzymes often present advantages in the synthesis of natural products with specific configurations. Farnesene is a pharmacologically active sesquiterpene with three natural Z/E configurations, among which the enzyme selectively responsible for the biosynthesis of (3Z,6E)-α-farnesene remains elusive. Herein, a sesquiterpene synthase TwSTPS1 biosynthesizing (3Z,6E)-α-farnesene as the major product was identified from Taxus wallichiana through genome mining. Utilizing molecular dynamics simulations and mutation analysis, the catalytic mechanism of TwSTPS1, especially Z/E configuration control, was explored. Moreover, the crucial residues associated with the specific catalytic activity of TwSTPS1 was elucidated through mutagenesis experiments. The findings contribute to our understanding of the Z/E configuration control by plant terpene synthases and also provide an alternative tool for manipulating (3Z,6E)-α-farnesene production using synthetic biology.
