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

摘要

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