Abstract

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.

Claims (28)

1. A composition of matter comprising:

a transgenic plant or part thereof including a modified protein having a lignocellulosic degrading protein and an intein fused within the lignocellulosic degrading protein, wherein the intein is thermally inducible to cause cis splicing of the modified protein by having a temperature of 50° C. or higher.

2. The composition of matter of claim 1 further comprising yeast.

3. The composition of matter of claim 1 , wherein the lignocellulosic degrading protein catalyzes a reaction selected from the group consisting of degrading lignin, degrading cellulose, and degrading hemicellulose.

4. The composition of matter of claim 1 , wherein the lignocellulosic degrading protein is an enzyme selected from the group consisting of cellulases having the classification E.C. 3.2.1.4, exocellobiohydrolases having the classification E.C. 3.2.1.91, glucosidases having the classification E.C. 3.2.1.21, endocellulases, exocellulases, xylanases, hemi-cellulase, ligninase, and lignin peroxidase.

5. The composition of matter of claim 1 wherein the lignocellulosic degrading protein is a cellulase.

6. The composition of matter of claim 1 further comprising at least one selected from the group consisting of other plant substrates, municipal waste, manufacturing by-products, prokaryotic cells and eukaryotic cells other than cells from the transgenic plant or part thereof.

7. The composition of matter of claim 1 further comprising a non-recombinant plant.

8. The composition of matter of claim 1 , wherein the transgenic plant or part thereof includes a second modified protein comprising a target protein fused to a second intein, wherein the second intein is thermally inducible to cause cis splicing of the second modified protein by having a temperature of 500° C. or higher.

9. The composition of matter of claim 8 , wherein the target protein is an enzyme or a segment thereof that catalyzes a reaction changing a sugar.

10. The composition of matter of claim 8 , wherein the target protein is an enzyme or a segment thereof that catalyzes a reaction producing ethanol.

11. The composition of matter of claim 8 , wherein the target protein is an enzyme or a segment thereof that catalyzes a reaction producing an intermediate in the production of ethanol.

12. The composition of matter of claim 8 , wherein the target protein is an enzyme or a segment thereof that catalyzes a reaction selected from the group consisting of reactions producing butanediol, producing ethanol, producing phenol, producing glycerol, producing ethylene, producing propylene, producing toluene, producing ethyl benzene, producing styrene, producing xylene, producing ethylene, producing glycol, producing butadiene, producing formaldehyde, producing isopropanol, producing acetone, producing butanediol, producing methanol, producing propanol, producing butanol, producing propanediol, producing a vitamin, producing methane, producing ethane, producing propane, producing butane, producing pentane, producing hexane, producing heptane, producing octane, producing benzene, degrading dextrin, degrading pectin, degrading lipids, degrading protein, degrading chitin, and saccharification.

13. The composition of matter of claim 8 further comprising at least one selected from the group consisting of other plant substrates, a non-recombinant plant, municipal waste, manufacturing by-products, prokaryotic cells and eukaryotic cells other than cells from the transgenic plant or part thereof.

14. A composition of matter comprising:

A transgenic plaint or part there of including a first gene encoding a modified protein having a lignocellulosic degrading protein and an intein fused within the lignocellulosic degrading protein, wherein the intein is thermally inducible to cause cis splicing of the modified protein by having a temperature of 50° C. or higher.

15. The composition of matter of claim 14 further comprising yeast.

16. The composition of matter of claim 14 , wherein the lignocellulosic degrading protein catalyzes a reaction selected from the group consisting of degrading lignin, degrading cellulose, and degrading hemicellulose.

17. The composition of matter of claim 14 , wherein the lignocellulosic degrading protein is an enzyme selected from the group consisting of cellulases having the classification E.C. 3.2.1.4, exocellobiohydrolases having the classification E.C. 3.2.1.91, glucosidases having the classification E.C. 3.2.1.21, endocellulases, exocellulases, xylanases, hemi-cellulase, ligninase, and lignin peroxidase.

18. The composition of matter of claim 14 wherein the lignocellulosic degrading protein is a cellulase.

19. The composition of matter of claim 14 further comprising at least one selected from the group consisting of other plant substrates, municipal waste, manufacturing by-products, prokaryotic cells and eukaryotic cells other than cells from the transgenic plant or part thereof.

20. The composition of matter of claim 14 further comprising a non-recombinant plant.

21. The composition of matter of claim 14 , wherein the transgenic plant or part thereof includes a second gene encoding a second modified protein comprising a target protein fused to a second intein, wherein the second intein is thermally inducible to cause cis splicing of the second modified protein by having a temperature of 50° C. or higher.

22. The composition of matter of claim 21 , wherein the target protein is an enzyme or a segment thereof that catalyzes a reaction changing a sugar.

23. The composition of matter of claim 21 , wherein the target protein is an enzyme or a segment thereof that catalyzes a reaction producing ethanol.

24. The composition of matter of claim 21 , wherein the target protein is an enzyme or a segment thereof that catalyzes a reaction producing an intermediate in the production of ethanol.

25. The composition of matter of claim 21 , wherein the target protein is an enzyme or a segment thereof that catalyzes a reaction selected from the group consisting of reactions producing butanediol, producing ethanol, producing phenol, producing glycerol, producing ethylene, producing propylene, producing toluene, producing ethyl benzene, producing styrene, producing xylene, producing ethylene, producing glycol, producing butadiene, producing formaldehyde, producing isopropanol, producing acetone, producing butanediol, producing methanol, producing propanol, producing butanol, producing propanediol, producing a vitamin, producing methane, producing ethane, producing propane, producing butane, producing pentane, producing hexane, producing heptane, producing octane, producing benzene, degrading dextrin, degrading pectin, degrading lipids, degrading protein, degrading chitin, and saccharification.
