Protein

UDP-glycosyltransferase 73B4

Gene

UGT73B4

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at transcript leveli

Functioni

Possesses quercetin 3-O-glucosyltransferase and low 7-O-glucosyltransferase activities in vitro. Also active in vitro on benzoates and benzoate derivatives. Can detoxify the explosive 2,4,6-trinitrotoluene in plant by forming O- or C-glucose conjugates.3 Publications

Catalytic activityi

UDP-glucose + a flavonol = UDP + a flavonol 3-O-D-glucoside.
