SS3

Soluble starch synthase 3, chloroplastic/amyloplastic

1230 amino acids

May account for most of the soluble starch synthase activity in the tubers. Contributes only a tiny percentage of the granule-bound activity, but may also contribute to the deposition of transient starch in chloroplasts of leaves.

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