Sysname
UDP-alpha-D-xylose:anthocyanidin-3-O-beta-D-glucoside 2'''-O-xylosyltransferase
Reaction(IUBMB)
UDP-alpha-D-xylose + an anthocyanidin 3-O-beta-D-glucoside = UDP + an anthocyanidin 3-O-beta-D-sambubioside [RN:R10256]
Reaction(KEGG)
Substrate
UDP-alpha-D-xylose [CPD:C00190];
anthocyanidin 3-O-beta-D-glucoside [CPD:C15539]
Product
UDP [CPD:C00015];
anthocyanidin 3-O-beta-D-sambubioside [CPD:C20467]
Comment
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.
