General annotation (Comments)

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

Plastidchloroplast By similarity. Plastidamyloplast By similarity. Note: Amyloplast or chloroplast, soluble By similarity. HAMAP-Rule MF_00484

Sequence similarities

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

Sequence caution

The sequence AAB02197.1 differs from that shown. Reason: Frameshift at position 629.
