UDP-alpha-D-glucose + delphinidin 3-O-glucosyl-5-O-(6-O-caffeoylglucoside)

UDP + delphinidin 3-O,3'-O-di-beta-D-glucosyl-5-O-(6-O-caffeoyl-beta-D-glucoside)

Gentiana triflora

Q8H0F2

in vitro, 50.9% of the activity with delphinidin 3,5-diglucoside

657052

UDP-glucose + an anthocyanidin

UDP + an anthocyanidin 3'-O-beta-D-glucoside

Gentiana triflora

Q8H0F2

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

657052

UDP-glucose + delphinidin

UDP + delphinidin 3'-glucoside

Gentiana triflora

Q8H0F2

poor substrate, 3.3% of the activity with delphinidin 3,5-diglucoside

UDP-glucose + delphinidin 3,5-di-O-beta-D-glucoside

UDP + delphinidin 3,5,7-tri-O-beta-D-glucoside

Gentiana triflora

Q8H0F2

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
