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.
L'invention concerne des nouveaux polypeptides présentant une activité (endo) xylanase. Ces polypetides peuvent dégrader de la cellulose dans des extraits végétaux ou des matières végétales. Les polypeptides peuvent cliver les polymères .beta.-D-xylane au niveau de liaisons internes (1-4) entre les motifs xylopyranosyl adjacents. On spécifie la séquence aminoacide et la séquence d'ADN codante, le poypeptide étant utilisé pour traiter de la cellulose dans la préparation de denrées alimentaires comestibles et de la nourriture pour animaux. Les polypeptides présentent une activité arabinoxylanase et xylosidase.
