摘要

Three novel polypeptides possessing (endo) beta -1,4-glucanase activity (EC 3.2.1.4) are disclosed which can degrade cellulose in plant extracts and plant materials. They are thus cellulases and can cleave beta -D-glucan polymers at internal (1-3, 1-4 or 1-6) bonds between adjacent glucose units. The amino acid sequence and encoding DNA sequence is given of all 3 glucanases (CEA, CEB and CEC) which were obtained from the fungal strain iTalaromyces emersonii / i . The glucanases can be used to treat cellulose in the preparation of edible foodstuffs and animal feed.
