Protein
Soluble starch synthase 3, chloroplastic/amyloplastic
Gene
SS3, SSIII
Organism
Solanum tuberosum (Potato)
Status
Reviewed - Annotation score: 3 out of 5 - Experimental evidence at protein leveli

Functioni

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.UniRule annotation

Catalytic activityi

ADP-glucose + (1,4-alpha-D-glucosyl)(n) = ADP + (1,4-alpha-D-glucosyl)(n+1).UniRule annotation
