EC | 2.4.1.360 | ||||||||
Accepted name: | 2-hydroxyflavanone C-glucosyltransferase | ||||||||
Reaction: | UDP-α-D-glucose + a 2′-hydroxy-β-oxodihydrochalcone = UDP + a 3′-(β-D-glucopyranosyl)-2′-hydroxy-β-oxodihydrochalcone | ||||||||
Glossary: | 2′-hydroxy-β-oxodihydrochalcone = 1-(2-hydroxyphenyl)-3-phenypropan-1,3-dione 3′-(β-D-glucopyranosyl)-2′-hydroxy-β-oxodihydrochalcone = 1-(3-(β-D-glucopyranosyl)-2-hydroxyphenyl)-3-phenylpropan-1,3-dione |

Other name(s): | OsCGT | ||||||||
Systematic name: | UDP-α-D-glucose:2′-hydroxy-β-oxodihydrochalcone C6/8-β-D-glucosyltransferase | ||||||||
Comments: | 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 1.14.14.162, flavanone 2-hydroxylase). The enzyme can also act on dihydrochalcones. The enzymes from citrus plants can catalyse a second C-glycosylation reaction at position 5. | ||||||||
