Glycosyltransferase that catalyzes the glucosylation of diverse hydroxycoumarins, naphthols, flavonoids, acylphloroglucinols, and pelargonidin (PubMed:26859691). Involved in fruit ripening by synthesizing acylphloroglucinol glucosides and anthocyanin (PubMed:26859691). a 2-acylphloroglucinol + UDP-alpha-D-glucose = a 2-acylphloroglucinol 1-O-beta-D-glucoside + UDP quercetin + UDP-alpha-D-glucose = H(+) + quercetin 3-O-beta-D-glucoside + UDP pelargonidin + UDP-alpha-D-glucose = pelargonidin 3-O-beta-D-glucoside + UDP Loss of fruit pigmentation, and substantial decrease of the levels of various acylphloroglucinol glucosides and an anthocyanin. Belongs to the UDP-glycosyltransferase family.
