FIELD: biotechnology.
SUBSTANCE: invention relates to biotechnology, specifically to steviol glycoside rebaudioside Z1, and can be used in food industry. Disclosed is a method of producing a steviol glycosides composition using recombinant polypeptides having UDM-glycosyl transferase activity, including 1,2-19-O-glucose-glycosylation activity and 1,2-13-O-glucose-glycosylation activity.
EFFECT: disclosed steviol glycoside can act as a sweetener.
