  • Stabilized transglutaminase and process for production thereof
    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.
    Type: Grant
