Display the reaction diagram Show all sequences 2.4.1.254UDP-beta-D-glucuronate + cyanidin 3-O-beta-D-glucoside highly specific with respect to the sugar donor UDP-GlcUA. Activity with other activated sugars such as UDP-Glc, UDP-Gal, and UDP-Xyl is very low. Wild-type enzyme activity toward delphinidin-3-O-glucoside is only 5% to 10% of the activity with cyanidin 3-O-beta-D-glucoside. A few specific amino acid residues as well as the overall size and shape of the acceptor pocket define substrate specificity Bellis perennis UDP + cyanidin 3-O-beta-(2-O-beta-D-glucuronosyl)-beta-D-glucoside - ?
Display the reaction diagram Show all sequences 2.4.1.254UDP-D-glucuronate + cyanidin 3-O-beta-D-glucoside both cyanidin-3-O-6''-malonylglucoside and cyanidin 3-O-glucoside are good substrates, suggesting that these anthocyanins may serve as physiological glucuronosyl acceptors in the production of glucuronosylated anthocyanins that are the origin of the red coloration of flowers of Bellis perennis Bellis perennis UDP + cyanidin 3-O-(2-O-beta-D-glucuronosyl)-beta-D-glucoside - ?
Display the reaction diagram Show all sequences 2.4.1.254UDP-D-glucuronate + cyanidin 3-O-beta-D-glucoside 50% of the activity with cyanidin-3-O-glucoside. The enzyme is highly specific for cyanidin 3-O-glucosides and UDP-D-glucuronate. The relative activities for UDP-D-glucose and UDP-D-galactose are less than 0.1% of the activity for UDP-D-glucuronate. The enzyme shows low activity with delphinidin 3-O-glucoside and is shows no or negligible activity towards pelargonidin 3-O-glucoside,cyanidin 3-O-3'',6''-O-dimalonylglucoside, pelargonidin 3,5-O-diglucoside, pelargonidin 3-O-6''-O-malonylglucoside-5-O-glucoside, quercetin 3-O-glucoside, quercetin 3-O-6''-O-malonylglucoside, daidzin, genistin, daidzin, genistin, 7-O-6''-O-malonylglucosides of daidzein and genistein, cyanidin, quercetin, daidzein, genistein, p-nitrophenyl beta-D-glucopyranoside Bellis perennis UDP + cyanidin 3-O-(2-O-beta-D-glucuronosyl)-beta-D-glucoside - ?
