The enzyme, characterized from the plant Panax ginseng, glucosylates the C-6 position of ginsenoside F1. The enzyme also glucosylates the C-20 position of protopanaxatriol, which forms ginsenoside F1 (cf. EC 2.4.1.363, ginsenoside 20-O-glucosyltransferase). However, unlike EC 2.4.1.367, ginsenoside 6-O-glucosyltransferase, it is not able to glucosylate the C-6 position of protopanaxatriol when position C-20 is not glucosylated.
