#This invention relates generally to enzymes, polynucleotides encoding the enzymes, the use of such polynucleotides and polypeptides and more specifically to enzymes having xylanase activity, e.g., catalyzing hydrolysis of internal β-1,4-xylosidic linkages or endo-β-1,4-glucanase linkages.

#Xylanases (e.g., endo-1,4-beta-xylanase, EC 3.2.1.8) hydrolyze internal β-1,4-xylosidic linkages in xylan to produce smaller molecular weight xylose and xylo-oligomers. Xylans are polysaccharides formed from 1,4-β-glycoside-linked D-xylopyranoses. Xylanases are of considerable commercial value, being used in the food industry, for baking and fruit and vegetable processing, breakdown of agricultural waste, in the manufacture of animal feed and in pulp and paper production. Xylanases are formed by fungi and bacteria.

#The present invention relates to xylanases and polynucleotides encoding them and methods of making and using them. Xylanase activity of the polypeptides of the invention encompasses enzymes having hydrolase activity, for example, enzymes capable of hydrolyzing glycosidic linkages present in xylan, e.g., catalyzing hydrolysis of internal β-1,4-xylosidic linkages. The xylanases of the invention can be used to make and/or process foods, feeds, nutritional supplements, textiles, detergents and the like. The xylanases of the invention can be used in pharmaceutical compositions and dietary aids. Xylanases of the invention are particularly useful in baking, animal feed, beverage and paper processes.
