  • Tannase, gene encoding same, and process for producing same
    Patent number: 8911984
    Abstract: Disclosed is a thermostable tannase derived from a microorganism. Specifically disclosed is a thermostable tannase derived from Aspergillus awamori or Aspergillus niger. A preferred embodiment of the tannase has the following chemoenzymatic properties: (1) activity: to act on a depside bond to thereby cause hydrolysis; (2) molecular weight: about 230,000 Da (as measured by gel filtration); and (3) thermal stability: stable at a temperature up to 65° C. (pH 5.0, 30 min.).
    Type: Grant
    Filed: November 25, 2013
    Date of Patent: December 16, 2014
    Assignee: Amano Enzyme Inc.
    Inventors: Megumi Nakagawa, Naoki Matsumoto, Hidoshi Amano, Shotaro Yamaguchi
