ID 2.4.1.286 DE chalcone 4'-O-glucosyltransferase. AN 4'CGT. CA (1) 2',4,4',6'-tetrahydroxychalcone + UDP-alpha-D-glucose = CA 2',4,4',6'-tetrahydroxychalcone 4'-O-beta-D-glucoside + H(+) + UDP. CA (2) 2',3,4,4',6'-pentahydroxychalcone + UDP-alpha-D-glucose = CA 2',3,4,4',6'-pentahydroxychalcone 4'-O-beta-D-glucoside + H(+) + UDP. CC -!- Isolated from the plant Antirrhinum majus (snapdragon). CC -!- Involved in the biosynthesis of aurones, plant flavonoids that CC provide yellow color to the flowers. DR Q33DV3, 4CGT_ANTMA ; //
