  • Mutant ?-glucosidase, enzyme composition for decomposing biomass, and method of producing sugar solution
    Patent number: 9080164
    Abstract: A ?-glucosidase exhibits high activity in the presence of biomass and has high thermal stability compared to conventional enzymes. The ?-glucosidase includes substitutions and/or deletions of amino acids, at least three amino acids selected from the group consisting of Glu39, Asp169, Arg170, Arg220, Tyr227, and Glu330, of the parent ?-glucosidase with other amino acids and exhibits a decomposition activity.
    Type: Grant
    Filed: January 14, 2014
    Date of Patent: July 14, 2015
    Assignee: Toray Industries, Inc.
    Inventors: Hiroyuki Kurihara, Katsushige Yamada, Kazuhiko Ishikawa, Yumiko Mishima, Yasunobu Wada, Yuji Kado
  • Method for producing glucosidase, enzyme composition, and method for hydrolyzing biomass
    Patent number: 9034627
    Abstract: A method for producing a mutant glucosidase includes introducing DNA encoding a secretion signal sequence and DNA encoding Asn-X-Ser or Asn-X-Thr into DNA encoding a glucosidase derived from a thermophile, and introducing the resulting DNA into a eukaryotic microorganism and expressing it as a secretory protein. An enzyme composition contains the mutant glucosidase.
