A method of predicting an intein insertion site in a protein that will lead to a switching phenotype is provided. The method includes identifying a plurality of C/T/S sites within the protein; selecting from the plurality of C/T/S/ sites those that are ranked 0.75 or higher by a support vector machine, within ten angstroms of the active site of the protein, and at or near a loop--sheet junction or a loop--helix junction. A method of controlling protein activity and hosts including proteins with controlled activity are also provided. Also, intein modified proteins and plants containing intein modified proteins are provided.


Transgenic plants that express CIVPS or intein modified proteins, compositions of matter comprising them, products of diverse applications made from the transgenic plants, methods to construct the transgenic plants containing CIVPS or intein modified genes, methods to express CIVPS or intein modified proteins in plants, and methods of using the transgenic plants.

Methods and compositions for increasing the starch content in green tissues of a plant are provided. The method comprises down-regulating me activity of starch degradation enzymes in a plant. The resulting transgenic plants of the invention have increased starch content in green tissues and exhibit a starch excess phenotype. In one embodiment the method involves manipulating a monocot plant to down-regulate the activity of a starch degradation enzyme. The plants are useful for improving the yield of free sugars from plant biomass and increase dried green tissue storage stability.


Transgenic plants that express CIVPS or intein modified proteins, compositions of matter comprising them, products of diverse applications made from the transgenic plants, methods to construct the transgenic plants containing CIVPS or intein modified genes, methods to express CIVPS or intein modified proteins in plants, and methods of using the transgenic plants.


Methods for regulating protein activity by fusing dimerization domains to target protein are provided. Chimeric proteins that include dimerization domains fused to target proteins for altering the activity of the target proteins are described. Engineered nucleic acids encoding chimeric proteins and hosts engineered to express engineered nucleic acids are also provided.


Nucleic acid promoters isolated from Panicum virgatum capable of transcriptional activation of heterologous nucleic acids are provided. Constructs, vectors and transgenic plants that include nucleic acid promoters are described. Methods for producing heterologous proteins in transgenic plants by transforming the plants with vectors and constructs are also provided.
