Recombinant thermostable enzyme for converting maltose into trehalose from Thermus aquaticus

摘要

Disclosed are a recombinant thermostable enzyme, which converts maltose into trehalose and is stable up to a temperature of about 80 DEG C. even when incubated at pH 7.0 for 60 min, a preparation of the enzyme, a DNA encoding the enzyme, a recombinant DNA containing the DNA, a transformant, and an enzymatic conversion method of maltose by using the enzyme.
