Protein

Soluble starch synthase 1, chloroplastic/amyloplastic

Gene
N/A
Organism
Solanum tuberosum (Potato)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at transcript leveli

Functioni

Plays a minor role in starch synthesis in storage organs (tubers), but may contribute to the deposition of transient starch in chloroplasts of leaves.

Catalytic activityi

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