LITERATURE
evolution
phylogenetic analysis classifies four of seven isolated genes as UDP glycosyltransferase (UGT) 84A subfamily proteins (UGT84A25a, -b, UGT84A26a, -b). In vitro enzyme assays show that the UGT84A proteins catalyze esterification of UDP-glucose and gallic acid to form 1-O-galloyl-beta-D-glucose. UGT84A25a and -26a also form 1-O-glucose esters of other structurally related hydroxybenzoic and hydroxycinnamic acids with a preference for hydroxybenzoic acids
metabolism
the UGT84A subfamily enzymes of Eucalyptus camaldulensis are responsible for constitutive production of 1-O-galloyl-beta-D-glucose, which is the first step of hydrolyzable tannin biosynthesis
