Xylanase polypeptide, a polynucleotide, a vector, a host cell, method of polypeptide production, method of use of polypeptide

摘要

Novel polypeptides possessing (endo) xylanase activity are disclosed which can degrade cellulose implant extracts and plant materials. The polypeptides can cleave beta -D-xylan polymers at internal (1-4) bonds between adjacent xylopyranosyl units. The amino acid sequence and encoding DNA sequence is given and the polypeptide was used to treat cellulose in the preparation of edible foodstuffs and animal feed. The polypeptides have both arabinoxylanase and xylosidase activity.
