  • Patent number: 10196623
    Abstract: 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.

  • Patent number: 9388422
    Abstract: In planta consolidated bioprocessing has the advantages of decreasing biomass pretreatment costs, utilizing excess plant protein production capacity for enzyme production, and decreasing mass transfer resistance of enzyme diffusion to its substrate. However, in planta expression of cell wall degrading (CWD) enzymes often leads to detrimental plant phenotypes that impact crop yield. To provide in planta CWD enzyme activity without any adverse phenotype, a thermostable xylanase, XynB (EC 3.2.1.8), was engineered with a thermoregulated intein, Tth-HB27 DnaE-1 (Tth intein), that controls its hydrolytic activity through conditional intein splicing. Maize plants expressing the heat inducible Tth intein-modified XynB developed normally, yet possessed enhanced post harvest glucose production from dried corn stover. Expression of CWD enzymes as dormant, intein-modified proteins that can be activated by heat treatment after harvest provides the basis for developing a novel cellulosic processing trait in plants.
