The present invention relates to a group of glycosyltransferase, and an application thereof. Specifically, provided is using glycosyltransferase GT29-32, GT29-33, GT29-34, GT29-4, GT29-5, GT29-7, GT29-9, GT29-11, GT29-13, GT29-17, GT29-18, GT29-19, GT29-20, GT29-21, GT29-22, GT29-23, GT29-24, GT29-25, GT29-36, GT29-37, GT29-42, GT29-43, GT29-45, GT29-46, PNUGT29-1, PNUGT29-2, PNUGT29-3, PNUGT29-4, PNUGT29-5, PNUGT29-6, PNUGT29-7, PNUGT29-8, PNUGT29-9, PNUGT29-14, and PNUGT29-15, as well as derived polypeptides thereof to catalyze the first glycosyl at position C-20, the first glycosyl at position C-6, and the first glycosyl at position C-3 of a tetracyclic triterpene compound substrate to elongate a carbohydrate chain, thereby obtaining a catalytic reaction of ginsenoside products such as ginsenoside Rg3, ginsenoside Rd, ginsenoside Rb1, ginsenoside Rb3, saponin DMGG, saponin DMGX, gypenoside LXXV, gypenoside XVII, gypenoside XIII, gypenoside IX, notoginsenoside U, and notoginsenoside R1, notoginsenoside R2, notoginsenoside R3, 3-O-β-(D-xylopyranosyl)-β-(D-glucopyranosyl)-PPD, 3-O-β-(D-xylopyranosyl)-β-(D-glucopyranosyl)-CK, 20-O-Glucosylginsenoside Rf, and Ginsenoside F3. Glycosyltransferase in the present invention can further be applied to construction of artificially synthesized ginsenoside, novel ginsenoside, and derivatives thereof.La présente invention concerne un groupe de glycosyltransférase, et une application associée.
