The present invention relates to new enzymes with improved properties and to compositions comprising these enzymes suitable for use in the production of a food, feed, or malt beverage product, such as in a brewing process.
1. A product selected from the group consisting of a food, a beverage, a feed, a paper product, a pulp product, and a biofuel wherein the product comprises:
a first enzyme exhibiting endo-1,4-β-xylanase activity, said first enzyme having the amino acid sequence of SEQ ID NO:1; and
a second enzyme exhibiting endo-1,3(4)-β-glucanase activity, said second enzyme having the amino acid sequence of SEQ ID NO:7.
2. The product according to claim 1 , further comprising at least one additional component chosen from the group consisting of an enzyme carrier, a stabilizer, and a preservative.
3. The product according to claim 1 , wherein the product has a xylanase activity from about 5000 U/g to about 8500 U/g.
4. The product according to claim 1 , wherein the product has a glucanase activity from about 10000 U/g to about 18000 U/g.
5. The according to claim 1 , wherein the product has a soluble arabinoxylan substrate to insoluble arabinoxylan substrate activity ratio (WE-AX/WU-AX) of less than about 7.0.
6. The product according to claim 1 , wherein the product has a temperature optimum from about 40° C. to about 70° C.
7. The product according to claim 1 , wherein the product comprises from about 200 to about 350 amino acids.
8. The product according to claim 1 , wherein at least one of the first enzyme and the second enzyme comprises a signal peptide.
9. A brewing mash comprising:
a first enzyme exhibiting endo-1,4-β-xylanase activity, said first enzyme having the amino acid sequence of SEQ ID NO:1;
a second enzyme exhibiting endo-1,3(4)-β-glucanase activity, said second enzyme having the amino acid sequence of SEQ ID NO:7; and
