|
| Other name(s): |
uridine 5′-diphosphate-xylose:anthocyanidin 3-O-glucose-xylosyltransferase; UGT79B1 |
| Systematic name: |
UDP-α-D-xylose:anthocyanidin-3-O-β-D-glucoside 2′′′-O-xylosyltransferase |
| Comments: |
Isolated from the plants Matthiola incana (stock) [1] and Arabidopsis thaliana (mouse-eared cress) [2]. The enzyme has similar activity with the 3-glucosides of pelargonidin, cyanidin, delphinidin, quercetin and kaempferol as well as with cyanidin 3-O-rhamnosyl-(1→6)-glucoside and cyanidin 3-O-(6-acylglucoside). There is no activity with other UDP-sugars or with cyanidin 3,5-diglucoside. |
