ID 2.4.1.363 DE ginsenoside 20-O-glucosyltransferase. AN UGT71A27. CA (20S)-protopanaxadiol + UDP-alpha-D-glucose = (20S)-ginsenoside C-K + CA H(+) + UDP. CC -!- The enzyme, characterized from the plant Panax ginseng, transfers a CC glucosyl moiety to the free C20(S)-OH group of dammarane derivative CC substrates, including protopanaxatriol, dammarenediol II, (20S)- CC ginsenoside Rh2, and (20S)-ginsenoside Rg3. CC -!- It does not act on the 20R epimer of protopanaxadiol, or on CC ginsenosides that are glucosylated at the C-6 position, such as CC ginsenoside Rh1 or ginsenoside Rg2.
