TALAROMYCES EMERSONII BETA-GLUCANASES

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....

Zusammenfassung:	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 Talaromyces emersonii. The glucanases can be used to treat cellulose in the preparation of edible foodstuffs and animal feed. Linvention concerne trois nouveaux polypeptides qui présentent une endoactivité .beta.-1,4-glucanase (EC 3.2.1.4) et qui sont en mesure de dégrader la cellulose dans des extraits de végétaux et des végétaux. Ce sont donc des cellulases qui peuvent couper des polymères de .beta.-D-glycanne au niveau des liaisons internes (1-3, 1-4 ou 1-6) en différents motifs glucoses adjacents. La séquence aminoacide et la séquence d'ADN codante concernent les trois glucanases (CEA, CEB et CEC) obtenues à partir de la souche fongique Talaromyces emersonii. Les glucanases peuvent être utilisées pour traiter la cellulose lors de la préparation de produits alimentaires et d'aliments pour animaux.
