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.
