Accepted name: ginsenoside F1 6-O-glucosyltransferase
Reaction: UDP-α-D-glucose + ginsenoside F1 = UDP + (20S)-ginsenoside Rg1
Glossary: ginsenoside F1 = 3β,6α,12β-trihydroxydammar-24-en-20-yl β-D-glucopyranoside
Other name(s): UGTPg101 (gene name)
Systematic name: UDP-α-D-glucose:ginsenoside F1 6-O-glucosyltransferase
Comments: 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, ginsenoside 20-O-glucosyltransferase). However, unlike EC, ginsenoside 6-O-glucosyltransferase, it is not able to glucosylate the C-6 position of protopanaxatriol when position C-20 is not glucosylated.
