    Functioni

    Broad spectrum multifunctional glucosyltransferase. Catalyzes the formation of flavonol 3-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

    Expressioni

    Tissue specificityi

    Strongly expressed in achenes, with lower expression levels detected in 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
