CC   -!- FUNCTION: Broad spectrum multifunctional glucosyltransferase. Catalyzes
CC       the formation of flavonol 3-O- and 4'-O-glucosides during fruit
CC       ripening. Accepted substrates include several flavonoids,
CC       hydroxycoumarins and beta-naphthols. Uses UDP-Glc as a sugar donor, but
CC       not UDP-Gal or UDP-GlcUA. May also be involved in detoxification of
CC       xenobiotics. {ECO:0000269|PubMed:18487633}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a flavonol + UDP-alpha-D-glucose = a flavonol 3-O-beta-D-
CC         glucoside + H(+) + UDP; Xref=Rhea:RHEA:22300, ChEBI:CHEBI:15378,

CC   -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC       Kinetic parameters:
CC         KM=3.5 uM for isorhamnetin {ECO:0000269|PubMed:18487633};
CC         KM=0.6 mM for UDP-glucose {ECO:0000269|PubMed:18487633};
CC         Vmax=2.8 nmol/sec/mg enzyme with isorhamnetin as substrate
CC         {ECO:0000269|PubMed:18487633};
CC         Vmax=2.7 nmol/sec/mg enzyme with UDP-glucose as substrate
CC         {ECO:0000269|PubMed:18487633};
CC         Note=The kinetic constants are determined for the recombinant GST-
CC         fusion protein. {ECO:0000269|PubMed:18487633};
CC       pH dependence:
CC         Optimum pH is 6.5. {ECO:0000269|PubMed:18487633};
CC       Temperature dependence:
CC         Optimum temperature is 45 degrees Celsius.
CC         {ECO:0000269|PubMed:18487633};
CC   -!- TISSUE SPECIFICITY: Strongly expressed in achenes and receptacles.
CC       {ECO:0000269|PubMed:18487633}.
CC   -!- DEVELOPMENTAL STAGE: The expression in receptacles is ripening-related,
CC       with highest expression detected in red fruit.
CC       {ECO:0000269|PubMed:18487633}.
CC   -!- INDUCTION: By de-achening. By injection with salicylic acid, with
CC       transcript levels increasing by a factor of 5-6 at 4 hours post-
CC       injection, remaining stable until 6 hours post-injection and falling
CC       below control levels at 8 hours post-injection. Down-regulated by
CC       synthetic auxin naphthaleneacetic acid (NAA).
CC       {ECO:0000269|PubMed:18487633}.
CC   -!- SIMILARITY: Belongs to the UDP-glycosyltransferase family.
CC       {ECO:0000255}.
