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

Tissue specificity

Leaves and immature seeds.

Miscellaneous

Three forms of soluble starch synthase were purified: RSS1, RSS2 and RSS3.

Sequence similarities

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

Sequence caution

The sequence AAD49850.1 differs from that shown. Reason: Frameshift at position 587.

The sequence BAA03739.1 differs from that shown. Reason: Frameshift at position 587.

The sequence BAA07396.1 differs from that shown. Reason: Frameshift at position 587.
