CC -!- FUNCTION: Plays a role in photosynthetic sucrose synthesis by
CC catalyzing the rate-limiting step of sucrose biosynthesis from UDP-
CC glucose and fructose- 6-phosphate. Involved in the regulation of carbon
CC partitioning in the leaves of plants. May regulate the synthesis of
CC sucrose and therefore play a major role as a limiting factor in the
CC export of photoassimilates out of the leaf. Plays a role for sucrose
CC availability that is essential for plant growth and fiber elongation.
CC {ECO:0000256|RuleBase:RU368006}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=beta-D-fructose 6-phosphate + UDP-alpha-D-glucose = H(+) +
CC sucrose 6(F)-phosphate + UDP; Xref=Rhea:RHEA:22172,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:57634, ChEBI:CHEBI:57723,
CC ChEBI:CHEBI:58223, ChEBI:CHEBI:58885; EC=2.4.1.14;
CC Evidence={ECO:0000256|ARBA:ARBA00001481,
CC ECO:0000256|RuleBase:RU368006};
CC -!- PATHWAY: Glycan biosynthesis; sucrose biosynthesis; sucrose from D-
CC fructose 6-phosphate and UDP-alpha-D-glucose: step 1/2.
CC {ECO:0000256|ARBA:ARBA00005027, ECO:0000256|RuleBase:RU368006}.
CC -!- SUBUNIT: Homodimer or homotetramer. {ECO:0000256|ARBA:ARBA00011774,
CC ECO:0000256|RuleBase:RU368006}.
CC -!- SIMILARITY: Belongs to the glycosyltransferase 1 family.
CC {ECO:0000256|ARBA:ARBA00006530, ECO:0000256|RuleBase:RU368006}.
