Function

function

This protein plays a role in synthesis of starch. It catalyzes the synthesis of the activated glycosyl donor, ADP-glucose from Glc-1-P and ATP.

Catalytic activity

Activity regulation

Activated by 3'phosphoglycerate, inhibited by orthophosphate. Allosteric regulation.

Pathway

Glycan biosynthesis; starch biosynthesis.

Expression

Tissue specificity

Leaves and tubers.

Induction

By sucrose.

Developmental stage

The strongest expression is seen in very small leaves (less than 1 cm in length) and decreases steadily as leaves become older. There is approximately 4- to 6-fold stronger expression in sink leaves relative to source leaves. Only minor variations in expression are seen during early stages of tuber development, however expression declines with increase in tuber size.
