  • Publication number: 20140242660
    Abstract: Provided is a chimeric isoprenoid synthase polypeptide including a first domain from a first isoprenoid synthase joined to a second domain from a second, heterologous, isoprenoid synthase, whereby the chimeric isoprenoid synthase is capable of catalyzing the production of isoprenoid reaction products that are not produced in the absence of the second domain of the second, heterologous, isoprenoid synthase. Also provided is a chimeric isoprenoid synthase polypeptide including an asymmetrically positioned heterologous domain, whereby the chimeric isoprenoid synthase is capable of catalyzing the production of isoprenoid reaction products that are not produced when the domain is positioned at its naturally-occurring site in the isoprenoid synthase polypeptide.

  • Patent number: 7186891
    Abstract: The invention features plant cells and plants that include a nucleic acid molecule encoding a chimeric isoprenoid synthase polypeptide including an asymmetrically positioned homologous domain. The chimeric isoprenoid synthases of the invention catalyze the production of isoprenoid reaction products that are not produced when the asymmetrically positioned homologous domain is positioned at its naturally-occurring site in an isoprenoid synthase polypeptide.

  • Patent number: 7084322
    Abstract: The present invention relates to a method for biosynthesizing the serotonin derivatives in plants, more particularly, a method for biosynthesizing the serotonin derivatives characterized by treating plants with inducers for serotonin derivative biosynthesis or by inducing over-expression of tyramine N-(hydroxy cinnamoyl)transferase in plants. The method of the present invention facilitates the production of serotonin derivatives such as feruloylserotonin and coumaroylserotonin that have activities of anticancer, anti-oxidation and promoting bone-formation. The serotonin derivatives prepared by the method above can be used either after being purified or as edible plants themselves.
