evolution
-
the enzyme belongs to the glycoside hydrolase family 1, molecular phylogenetic tree based on amino acid sequences, overview
physiological function
-
in delphinium petals, an acyl-glucose, 1-O-beta-D-vanillyl-glucose, acts as the donor molecule in the glucosyl transfer reaction at the 7 position of anthocyanin
physiological function
cultivar Cassis Pink accumulates delphinidin 3-O-rutinoside due to a defect in AA7GT expression or function
physiological function
blue colors of delphinium are derived from cyanodelphin that has three modifications of glucose moieties and two of 4-hydroxybenzoyl residues compared with violdelphin. Isoforms AA7BG-GT1 and AA7BG-GT2 add the second glucosyl residue
