Glossary: phlorisobutyrophenone = 2-methyl-1-(2,4,6-trihydroxyphenyl)propan-1-one
phlorisovalerophenone = 3-methyl-1-(2,4,6-trihydroxyphenyl)butan-1-one
Other name(s): UGT71K3
Systematic name: UDP-α-D-glucose:2-acylphloroglucinol 1-O-β-glucosyltransferase
Comments: Isolated from strawberries (Fragaria × ananassa). Acts best on phloroisovalerophenone and phlorobutyrophenone but will also glycosylate many other phenolic compounds. A minor product of the reaction is the 5-O-β-D-glucoside
