Protein Name:
Sucrose-phosphate synthase 4
|
UniprotKB/SwissProt ID: F4JLK2 (F4JLK2)
Gene Name:
SPS4
Organism: Arabidopsis thaliana (Mouse-ear cress)
Function: Plays a role in photosynthetic sucrose synthesis by catalyzing the rate-limiting step of sucrose biosynthesis from UDP-glucose and fructose- 6-phosphate (By similarity). Involved in the regulation of carbon partitioning in the leaves of plants (By similarity). May regulate the synthesis of sucrose and therefore play a major role as a limiting factor in the export of photoassimilates out of the leaf (By similarity). Plays a role for sucrose availability that is essential for plant growth and fiber elongation (By similarity)
