Estimating the term…
The present invention relates to plant cells and plants, which are genetically modified, whereby the genetic modification leads to an increase in the activity of a starch-phosphorylating OK1 protein in comparison to the corresponding wild type plant cells or wild type plants that have not been genetically modified. In addition, the present invention concerns means and methods for the manufacture of such plant cells and plants. These types of plant cells and plants synthesise a modified starch. Therefore, the present invention also concerns the starches synthesised from the plant cells and plants according to the invention, methods for manufacturing these starches, and the manufacture of starch derivatives of these modified starches, as well as flours containing starches according to the invention. Furthermore, the present invention also relates to nucleic acids, coding starch-phosphorylating OK1 proteins, vectors, host cells, plant cells, and plants containing such nucleic acid molecules. In addition, the present invention relates to OK1 proteins that have starch-phosphorylating activity.
A modified starch obtainable from a genetically modified plant comprising one or more genetically modified plant cells, which exhibit increased activity in at least one OK1 protein in comparison to corresponding wild type plant cells that have not been genetically modified.
A method of manufacturing a modified starch comprising extracting the starch from a genetically modified plant cell, which exhibits increased activity in at least one OK1 protein in comparison to corresponding wild type plant cells that have not been genetically modified.
Flour obtainable from plant cells, which exhibit increased activity in at least one OK1 protein in comparison to corresponding wild type plant cells that have not been genetically modified.
A protein, which exhibits starch-phosphorylating activity and needs phosphorylated starch as a substrate.
A protein, which needs phosphorylated starch as a substrate and transfers the residual phosphate of ATP to phosphorylated starch.
