Protein
UDP-glucose flavonoid 3-O-glucosyltransferase 7
Gene
GT7
Organism
Fragaria ananassa (Strawberry)
Status
Reviewed - Annotation score: 3 out of 5 - Experimental evidence at protein leveli

Functioni

Broad spectrum multifunctional glucosyltransferase. Catalyzes the formation of flavonol 3-O- and 4'-O-glucosides during fruit ripening. Accepted substrates include several flavonoids, hydroxycoumarins and beta-naphthols. Uses UDP-Glc as a sugar donor, but not UDP-Gal or UDP-GlcUA. May also be involved in detoxification of xenobiotics.1 Publication

Catalytic activityi

UDP-glucose + a flavonol = UDP + a flavonol 3-O-D-glucoside.1 Publication

Kineticsi

The kinetic constants are determined for the recombinant GST-fusion protein.1 Publication

pH dependencei

Optimum pH is 6.5.1 Publication

Temperature dependencei

Optimum temperature is 45 degrees Celsius.1 Publication

    Expressioni

    Tissue specificityi

    Strongly expressed in achenes and receptacles.1 Publication

    Developmental stagei

    The expression in receptacles is ripening-related, with highest expression detected in red fruit.1 Publication

    Inductioni

    By de-achening. By injection with salicylic acid, with transcript levels increasing by a factor of 5-6 at 4 hours post-injection, remaining stable until 6 hours post-injection and falling below control levels at 8 hours post-injection. Down-regulated by synthetic auxin naphthaleneacetic acid (NAA).1 Publication
