Abstract
In the quest for innovative cancer therapeutics, paclitaxel remains a cornerstone in clinical oncology. However, its complex biosynthetic pathway, particularly the intricate oxygenation steps, has remained a puzzle in the decades following the characterization of the last taxane hydroxylase. The high divergence and promiscuity of enzymes involved have posed significant challenges. In this study, we adopted an innovative approach, combining in silico methods and functional gene analysis, to shed light on this elusive pathway. Our molecular docking investigations using a library of potential ligands uncovered TB574 as a potential missing enzyme in the paclitaxel biosynthetic pathway, demonstrating auspicious interactions. Complementary in vivo assays utilizing engineered S. cerevisiae strains as novel microbial cell factory consortia not only validated TB574's critical role in forging the elusive paclitaxel intermediate, T5αAc-1β,10β-diol, but also achieved the biosynthesis of paclitaxel precursors at an unprecedented yield including T5αAc-1β,10β-diol with approximately 40 mg/L. This achievement is highly promising, offering a new direction for further exploration of a novel metabolic engineering approaches using microbial consortia. In conclusion, our study not only furthers study the roles of previously uncharacterized enzymes in paclitaxel biosynthesis but also forges a path for pioneering advancements in the complete understanding of paclitaxel biosynthesis and its heterologous production. The characterization of T1βOH underscores a significant leap forward for future advancements in paclitaxel production using heterologous systems to improve cancer treatment and pharmaceutical production, thereby holding immense promise for enhancing the efficacy of cancer therapies and the efficiency of pharmaceutical manufacturing.
