UniProtKB - C3W7B0 (CGT_ORYSI)
Protein
UDP-glycosyltransferase CGT
Gene
CGT
Organism
Oryza sativa subsp. indica (Rice)
Status
Functioni
UDP-glucose-dependent glucosyltransferase catalyzing the c-glucosylation of 2-hydroxyflavanones. Acts preferentially on the dibenzoylmethane tautomers formed in equilibrium with 2-hydroxyflavanones. No activity with naringenin or naringenin chalcone.
1 PublicationCatalytic activityi
- a 3'-hydro-2'-hydroxy-β-oxodihydrochalcone + UDP-α-D-glucose = a 3'-(β-D-glucopyranosyl)-2'-hydroxy-β-oxodihydrochalcone + H+ + UDP1 PublicationEC:2.4.1.3601 PublicationThis reaction proceeds in the forward1 Publication direction.
Kineticsi
kcat is 0.76 sec(-1) with 2,5,7-trihydroxyflavanone as substrate. kcat is 3.13 sec(-1) with 2-hydroxynaringenin as substrate. kcat is 0.75 sec(-1) with 2',4',6'-trihydroxydihydrochalcone as substrate. kcat is 10.84 sec(-1) with phoretin as substrate. kcat is 0.11 sec(-1) with 2,4,6-trihydroxybenzophenone as substrate.1 Publication
