Pachymic acid production has gained significant attention within the pharmaceutical industry due to its potent anti-tumor and anti-inflammatory properties. This bioactive triterpenoid is primarily found in Poria cocos, a medicinal fungus widely utilized in traditional medicine. However, extracting this compound from natural sources remains difficult and resource-intensive. Consequently, researchers have focused on synthetic biology to find more efficient solutions. A breakthrough study has now identified the CYP5035 gene as a key driver for biosynthetic success.
The research team utilized a multi-omics approach to pinpoint the specific cytochrome P450 gene responsible for the synthesis of this triterpenoid. By treating fungal mycelia with Methyl jasmonate (MeJA), they observed a strong correlation between CYP5035 expression and pachymic acid accumulation. Furthermore, they successfully performed heterologous expression of this gene in Saccharomyces cerevisiae. This process transformed the yeast into a biological factory for the compound.
In addition to gene discovery, the scientists optimized the yeast strain through redox partner enhancement and dynamic flux redirection. These metabolic engineering strategies significantly boosted the overall yield. Therefore, this microbial platform represents a major step toward the green and sustainable manufacture of complex medicinal molecules. This achievement not only clarifies the molecular basis of fungal triterpenoid synthesis but also ensures a reliable supply for future clinical applications.
Pachymic acid is a major bioactive component of Poria cocos. It is highly valued for its anti-tumor, anti-inflammatory, and sedative activities, making it a target for oncology research and natural product pharmacology.
The discovery of the CYP5035 gene allows for the heterologous production of pachymic acid in yeast. This method is more sustainable than traditional extraction, as it does not rely on pine wood-based cultivation or limited natural fungal supplies.
Yeast, specifically Saccharomyces cerevisiae, is a well-understood host for metabolic engineering. It can be modified to express foreign genes, enabling the efficient and scalable production of complex secondary metabolites found in plants and fungi.
