Function

Involved in synthesis of starch. Catalyzes the synthesis of ADP-glucose, a molecule that serves as an activated glycosyl donor for alpha-1,4-glucan synthesis. The chloroplastic isoform 1 is essential for starch synthesis in leaf chloroplasts and the cytosolic isoform 2 for synthesis in seed endosperm
