CC   -!- FUNCTION: Sucrose-cleaving enzyme that provides UDP-glucose and
CC       fructose for various metabolic pathways.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=an NDP-alpha-D-glucose + D-fructose = a ribonucleoside 5'-
CC         diphosphate + H(+) + sucrose; Xref=Rhea:RHEA:16241,
CC         ChEBI:CHEBI:15378, ChEBI:CHEBI:17992, ChEBI:CHEBI:37721,
CC         ChEBI:CHEBI:57930, ChEBI:CHEBI:76533; EC=2.4.1.13;
CC   -!- SIMILARITY: Belongs to the glycosyltransferase 1 family. Plant sucrose
CC       synthase subfamily. {ECO:0000305}.
