Function

function

Plays a role in photosynthetic sucrose synthesis by catalyzing the rate-limiting step of sucrose biosynthesis from UDP-glucose and fructose- 6-phosphate. Involved in the regulation of carbon partitioning in the leaves of plants. 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. Plays a role for sucrose availability that is essential for plant growth and fiber elongation.

Catalytic activity

Pathway

Glycan biosynthesis; sucrose biosynthesis; sucrose from D-fructose 6-phosphate and UDP-alpha-D-glucose: step 1/2.
