CC -!- FUNCTION: Plays a major 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 Required for nectar secretion. {ECO:0000269|PubMed:10998187,
CC ECO:0000269|PubMed:17415671, ECO:0000269|PubMed:21309792,
CC ECO:0000269|PubMed:24670640}.
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 seeds, stems, rosette leaves, flowers
CC and siliques. Highly expressed in maturing nectaries.
CC {ECO:0000269|PubMed:21309792, ECO:0000269|PubMed:24670640}.
CC -!- INDUCTION: Circadian-regulated, with the highest expression at the end
CC of the light period and the lowest at the end of the dark period (in 12
CC hours light/12 hours dark cycle). Induced by cold (at protein level).
CC {ECO:0000269|PubMed:21309792}.
CC -!- PTM: Phosphorylated at Ser-152 upon sucrose supply.
CC {ECO:0000269|PubMed:24924143}.
CC -!- DISRUPTION PHENOTYPE: Loss of nectar secretion accompanied by starch
CC accumulation in nectaries. {ECO:0000269|PubMed:24670640}.
CC -!- MISCELLANEOUS: Plants silencing SPS1 show reduced shoot growth, leaf
CC fresh weight and dry weight, and decreased leaf starch, leaf sugar
CC levels and sucrose export rates (PubMed:10998187 and PubMed:21309792).
CC Tobacco plants overexpressing Arabidopsis SPS1 show increased stem
CC height and diameter, increased total dry weight and elevated
CC concentrations of sink sucrose pools (PubMed:17415671).
CC {ECO:0000305|PubMed:17415671}.
CC -!- SIMILARITY: Belongs to the glycosyltransferase 1 family. {ECO:0000305}.
