Flavonol-3-O-glukozid glukoziltransferaza (EC 2.4.1.239, UDP-glukoza:flavonol-3-O-glukozid 2-O-beta-D-glukoziltransferaza) je enzim sa sistematskim imenom UDP-glukoza:flavonol-3-O-beta-D-glukozid 2-O-beta-D-glukoziltransferaza.^[1] Ovaj enzim katalizuje sledeću hemijsku reakciju

UDP-glukoza + flavanol3-O-beta-D-glukozid ${\displaystyle \rightleftharpoons }$ UDP + flavanol3-O-beta-D-glukozil-(1->2)-beta-D-glukozid

Ovaj enzim je jedna od tri specifična glukoziltransferaze u grašku (Pisum sativum) koji uspešno dodaje beta-D-glukozilnu grupu prvo na O-3 kampferola, a zatim na O-2 prethodno dodate glukozilne grupe.
