COLD-ACTIVE BETA-GALACTOSIDASE, A METHOD OF PRODUCING SAME AND USE OF SUCH ENZYME

摘要

There is provided a novel cold-active beta-galactosidaseenzyme specific for lactose. The enzyme is thus useful in e.g. the foodindustryfor catalyzing at low temperatures the hydrolysis of lactose disaccharideinto its constituent monosaccharides, glucose and galactose. Thepresent invention further provides a method of producing the cold-activebeta-galactosidase by recombinant DNA technology.
