DNAs encoding enzymes, recombinant DNAs and enzymes, transformants, and methods of making and using the same

摘要

DNAs, recombinant DNAs and recombinant enzymes, transformants, and methods for producing enzymes that encode trehalose-producing enzymes from non-reducing sugars having trehalose structure as a terminal unit and having a degree of glucose polymerization of 3 or more; Serves the purpose. These allow trehalose to be produced on a large scale relatively easily at low cost. The trehalose thus produced can be satisfactorily used in various foods, cosmetics and medicines.
