  • MUTANT BETA-GLUCOSIDASE VARIANTS WITH INCREASED THERMOSTABILITY
    Publication number: 20190071658
    Abstract: The invention relates to mutant variants of the ?-glucosidase Cgl T from Thermoanaerobacter brockii and nucleic acids for producing the same. Said mutant variants show significantly increased thermostability and enzyme activity. Furthermore, the invention provides vectors, host cells and methods for producing said mutant variants of the ?-glucosidase Cgl T. Also provided are artificial cellulosomes comprising the mutant variants of the ?-glucosidase Cgl T and methods for the enzymatic hydrolysis of cellulosic biomass comprising said artificial cellulosomes and/or said mutant variants of the ?-glucosidase Cgl T.
