  • Protein having B-glucosidase activity and uses thereof
    Patent number: 10125355
    Abstract: By combination of hydrophobic chromatography and strongly basic anion-exchange chromatography, a novel, highly hydrophobic ?-glucosidase was successfully identified from Acremonium cellulolyticus. Further, a gene corresponding to the identified ?-glucosidase was isolated. When multiple modifications were introduced into the base sequence of the gene, the gene was successfully expressed in Trichoderma viride at a high level, and the expression product successfully exhibited a high ?-glucosidase activity.
    Type: Grant
    Filed: December 19, 2014
    Date of Patent: November 13, 2018
    Assignee: MEIJI SEIKA PHARMA CO., LTD.
    Inventors: Fumikazu Yokoyama, Kengo Yokoyama, Nobuko Mazuka
