USE OF GLYCOSIDE HYDROLASE 61 FAMILY PROTEINS IN PROCESSING OF CELLULOSE

摘要

The invention provides recombinant GH61 proteins obtained from Myceliophtora thermophila, and nucleic acids that encode such proteins. The invention also provides protein fractions isolated from M. thermophila supernatant that have GH61 protein activity. These preparations can be used to increase yield of products from reactions in which a cellulose-containing substrate undergoes saccharification by one or more cellulase enzymes, such as endoglucanase, β-glucosidase, or cellobiohydrolase. Combinations of GH61 protein and cellulases can be used to break down cellulosic biomass into fermentable sugars in the production of ethanol.
