| Research Abstract |
To improve the productivity of alkaloids in our microbial system, we modified the biosynthetic pathway and established the cytochrome P450 expression system in E. coli cells. Theses results enable the production of large amounts of alkaloids in E. coli cells. For the production of pharmaceutical important alkaloid narcotic, the biosynthetic genes were isolated from opium poppy, and were expressed in E. coli cells. We generated an E. coli strain that produce thebaine, introducing thebaine biosynthetic genes from reticuline in the reticuline producing E. coli cells. LC-MS analysis showed that the intermediates accumulated in the culture, but thebain was not detected. We have examined the production condition of thebaine.
