ENZYME entry: EC

Accepted Name
2-hydroxyflavanone C-glucosyltransferase.
Reaction catalysed
UDP-alpha-D-glucose + a 2'-hydroxy-beta-oxodihydrochalcone <=> UDP + a 3'-(beta-D-glucopyranosyl)-2'-hydroxy-beta-oxodihydrochalcone
  • The enzyme has been characterized in Oryza sativa (rice), various Citrus spp., Glycine max (soybean), and Fagopyrum esculentum (buckwheat).
  • Flavanone substrates require a 2-hydroxy group.
  • The meta-stable flavanone substrates such as 2-hydroxynaringenin exist in an equilibrium with open forms such as 1-(4-hydroxyphenyl)- 3-(2,4,6-trihydroxyphenyl)propane-1,3-dione, which are the actual substrates for the glucosyl-transfer reaction (see EC
  • The enzyme can also act on dihydrochalcones.
  • The enzymes from citrus plants can catalyze a second C-glycosylation reaction at position 5.
