| 2.4.1.238 | UDP-alpha-D-glucose + delphinidin 3-O-glucosyl-5-O-(6-O-caffeoylglucoside) |
in vitro, 50.9% of the activity with delphinidin 3,5-diglucoside |
Gentiana triflora |
UDP + delphinidin 3-O,3'-O-di-beta-D-glucosyl-5-O-(6-O-caffeoyl-beta-D-glucoside) |

| 2.4.1.238 | UDP-glucose + an anthocyanidin |
strict substrate specificity, 3'GT specifically glucosylates the 3'-hydroxy group of delphinidin-type anthocyanins containing glucose groups at the 3 and 5 positions and specifically uses UDP-glucose as the sugar donor, 3GT strictly requires three hydroxy groups on the B-ring for its substrates |

| 2.4.1.238 | UDP-glucose + delphinidin |
poor substrate, 3.3% of the activity with delphinidin 3,5-diglucoside |

? |
| 2.4.1.238 | UDP-glucose + delphinidin 3,5-di-O-beta-D-glucoside |
3'GT glucosylates the 3'-hydroxy group of delphinidin 3,5-diglucoside, 2fold higher activity than with delphinidin 3-O-glucosyl-5-O-(6-O-caffeoylglucoside) as substrate |
