Patent

CA 2669453

The invention relates to polypeptides having glucanase, e.g., endoglucanase, mannanase, xylanase activity or a combination of these activities, and polynucleotides encoding them. In one aspect, the glucanase activity is an endoglucanase activity (e.g., endo-1,4-beta-D-glucan 4-glucano hydrolase activity) and comprises hydrolysis of 1,4-beta-D-glycosidic linkages in cellulose, cellulose derivatives (e.g., carboxy methyl cellulose and hydroxy ethyl cellulose) lichenin, beta- 1,4 bonds in mixed beta- 1,3 glucans, such as cereal beta-D-glucans or xyloglucans and other plant material containing cellulosic parts. In addition, methods of designing new enzymes and methods of use thereof are also provided. In alternative aspects, the new glucanases e.g., endoglucanases, mannanases, xylanases have increased activity and stability, including thermotolerance or thermostability, at increased or decreased pHs and temperatures.

L'invention concerne des polypeptides ayant du glucanase, par exemple, de l'endoglucanase, du mannanase, une activité xylanase ou une combinaison de ces activités, et des polynucléotides les codant. Selon un aspect, l'activité glucanase est une activité endoglucanase (par exemple, l'activité d'endo-1,4-bêta-D-glucan 4-glucano hydrolase) et comprend l'hydrolyse de liaisons 1,4-bêta-D-glycosidique dans une cellulose, des dérivés de cellulose (par exemple, la carboxyméthylcellulose et l'hydroxyéthylcellulose), la lichénine, les liaisons bêta-1,4 dans des bêta-1,3-glucanes mélangés, tels que des bêta-D-glucanes de céréale ou des xyloglucanes et toute autre matière végétale contenant des parties cellulosiques. De plus, des procédés de conception de nouvelles enzymes et des procédés d'utilisation de celles-ci sont également fournis. Selon d'autres aspects, les nouvelles glucanases par exemple des endoglucanases, des mannanases, des xylanases ont une activité et une stabilité accrues, y compris une thermotolérance ou une thermostabilité, à des pH et des températures accru(e)s ou diminué(e)s.
