Metabolite Identification
Common Nameisoepoxydon
DescriptionIsoepoxydon is a secondary metabolite classified within the chemical class of epoxides. It plays a crucial role in the biosynthesis of patulin, a mycotoxin produced by various Penicillium species. The chemical structure of isoepoxydon features an epoxide functional group, which is integral to its reactivity and biological activity. In the patulin biosynthetic pathway, isoepoxydon is synthesized from 6-methylsalicylic acid through the action of the enzyme isoepoxydon dehydrogenase (IDH), which is encoded by the idh gene. This enzyme catalyzes the conversion of isoepoxydon to the next intermediate in the pathway, thus facilitating the production of patulin. Studies have demonstrated the expression levels of the idh gene and 6-methylsalicylic acid synthase (6-MSAS) as key factors in patulin production by fungi such as Penicillium expansum (PMID:35528279 , PMID:26788884 ). Furthermore, specific detection methods targeting the idh gene have been developed to identify patulin-producing strains, highlighting its significance in fungal taxonomy and food safety (PMID:30903915 , PMID:18095762 ). Overall, isoepoxydon is a pivotal compound in the metabolic pathways associated with mycotoxin biosynthesis.
