|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
- 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 22.214.171.124).
- The enzyme can also act on dihydrochalcones.
- The enzymes from citrus plants can catalyze a second C-glycosylation
reaction at position 5.
