Abstract
Disclosed are a DNA encoding an enzyme which releases trehalose from non-reducing saccharides having a trehalose structure as an end unit and having a degree of glucose polymerization of 3 or higher, recombinant DNA and enzyme, transformant, and their preparations and uses. These facilitate the industrial-scale production of trehalose with a relative easiness and low cost, and trehalose thus obtained can be satisfactorily used in a variety of food products, cosmetics and pharmaceuticals.
Claims26
A DNA molecule, which is derived from a microorganism selected from the genera consisting of Rhizobium, Arthrobacter, Brevibacterium, and Micrococcus, encoding an enzyme which releases trehalose from a non-reducing saccharide having a trehalose structure as an end unit and having a degree of glucose polymerization of 3 or higher.
