- In enzymology, a flavonol 3-O-glucosyltransferase (EC 2.4.1.91) is an enzyme that catalyzes the chemical reaction UDP-glucose + a flavonol UDP + a flavonol 3-O-beta-D-glucoside Thus, the two substrates of this enzyme are UDP-glucose and flavonol, whereas its two products are UDP and flavonol 3-O-beta-D-glucoside. The flavonoids that can act as substrates within this reaction include quercetin, kaempferol, dihydrokaempferol, kaempferid, fisetin, and isorhamnetin. Flavonol 3-O-glucosyltransferase is a hexosyl group transfer enzyme. This enzyme is known by the systematic name UPD-glucose:flavonol 3-O-D glucosyltransferase, and it participates in flavonoid biosynthesis and causes the formation of anthocyanins. Anthocyanins produce a purple color in the plant tissues that they are present in. It is an enzyme found most notably in grapes (Vitis vinifera). This enzyme is found within a number of other plants as well—such as snapdragons (Antirrhinum majus), kale (Brassica oleracea), and grapefruit (Citrus x paradisi). (en)
- La flavonolo 3-O-glucosiltransferasi è un enzima appartenente alla classe delle transferasi, che catalizza la seguente reazione: UDP-glucosio + un flavonolo ⇄ UDP + un flavonolo 3-O-β-D-glucoside L'enzima agisce su una varietà di flavonoli, tra i quali la quercetina ed il quercetin 7-O-glucoside. È diversa dalla flavone 7-O-beta-glucosiltransferasi (numero EC 2.4.1.81). (it)
