General annotation (Comments)

Function

May be involved in starch synthesis in endosperm amyloplasts and contribute to the deposition of transient starch in chloroplasts of leaves. Ref.1

Catalytic activity

ADP-glucose + (1,4-alpha-D-glucosyl)(n) = ADP + (1,4-alpha-D-glucosyl)(n+1). HAMAP-Rule MF_00484

Pathway

Glycan biosynthesis; starch biosynthesis. HAMAP-Rule MF_00484

Subcellular location

Plastidamyloplast. Plastidchloroplast. Note: Amyloplast or chloroplast, granule-bound and soluble. Ref.1 Ref.5

Tissue specificity

Expressed in endosperm, leaves, and weakly in roots. Ref.1 Ref.5

Developmental stage

Expressed in developing caryopsis at 1 to 20 days after flowering. Expressed in the pericarp and endosperm at 5 and 5 to 10 days after flowering respectively. Ref.1

Sequence similarities

Belongs to the glycosyltransferase 1 family. Bacterial/plant glycogen synthase subfamily.
