| Outline of Final Research Achievements |
To develop the medicinal plants containing large amounts of useful metabolites, in this study I attempted to increase the contents of medicinally-important compounds in the plants by inhibiting the activity of metabolic enzyme through the expression of their neutralizing antibodies.
I first prepared the antigen Scutellaria peroxidases 1 and 2 which metabolite baicalein in Scutellaria baicalensis. Scutellaria peroxidases 1 and 2 were expressed in E.coli. Because the recombinant Scutellaria peroxidases 1 and 2 lacked the enzyme activity, refolding of the recombinant proteins was conducted.When the recombinant proteins were refolded in the presence of hemin and urea, the refolded proteins showed peroxidase activity. Now, I injected the refolded proteins into mice to prepare monoclonal antibodies. In addition, I conducted the expression of morphine peroxidase which degrades morphine in opium poppy, and started to prepare its anbodies.
