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 (By similarity). {ECO:0000250}.
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 -!- ACTIVITY REGULATION: Activity is regulated by phosphorylation and
CC moderated by concentration of metabolites and light. {ECO:0000250}.
CC -!- PATHWAY: Glycan biosynthesis; sucrose biosynthesis; sucrose from D-
CC fructose 6-phosphate and UDP-alpha-D-glucose: step 1/2.
CC -!- SUBUNIT: Homodimer or homotetramer. {ECO:0000250}.
CC -!- TISSUE SPECIFICITY: Expressed in germinating seeds.
CC {ECO:0000269|PubMed:21683881}.
CC -!- DEVELOPMENTAL STAGE: Highly expressed in source leaves and at low
CC levels in sink leaves. {ECO:0000269|PubMed:21683881}.
CC -!- INDUCTION: Circadian-regulated, with the highest expression 1 hour
CC before the beginning of light period (in 14 hours light/10 hours dark
CC cycle). {ECO:0000269|PubMed:21683881}.
CC -!- SIMILARITY: Belongs to the glycosyltransferase 1 family. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=BAF07124.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
