1. A method for synthesizing a mixture stevioside and rebaudioside KA from rubusoside, the method comprising:
preparing a reaction mixture comprising rubusoside, substrates selected from the group consisting of sucrose, uridine diphosphate (UDP) and uridine diphosphate-glucose (UDP-glucose), a UDP-glycosyltransferase selected from the group consisting of EUGT11 and a UDP-glycosyltransferase fusion enzyme; and incubating the reaction mixture for a sufficient time to produce a mixture of stevioside and rebaudioside KA, wherein a glucose is covalently coupled to C2′-19-O-glucose of rubusoside to produce rebaudioside KA, and a glucose is convalently coupled to C2′-13-O-glucose of rubusoside to produce stevioside. |
