  • Patent number: 9487765
    Abstract: Disclosed is a transglutaminase having excellent stability. Also disclosed is a process for producing the transglutaminase. Specifically disclosed is a stabilized transglutaminase, which has such a structure in which a pro-sequence peptide of transglutaminase is bound to a mature transglutaminase. Also specifically disclosed is a process for producing stabilized transglutaminase, which includes the steps of culturing a microorganism capable of producing transglutaminase under the conditions where transglutaminase can be produced; and separating and collecting matured transglutaminase having a pro-sequence peptide bound thereto from a culture medium.

  • Patent number: 8770741
    Abstract: A glasses-type shutter holder may include left and right temple parts connected respectively to left and right frame end parts of frame. The left and right temple parts may be foldable respectively with respect to the left and right frame end parts in accordance with movement, for each frame end part and temple part pair, of a contact position at which a movement part provided with one of the temple part and the frame end part of the pair is in contact with a contact part of the other of the temple part and the frame end part of the pair. For each of the pairs, the contact part is in contact with the movement part when the temple part is unfolded to a maximum degree, and a maximum degree of opening of the temple part is varied in accordance with the movement of the movable part.
