Protein

Soluble starch synthase 1, chloroplastic/amyloplastic

Gene
N/A
Organism
Solanum tuberosum (Potato)
Status
Reviewed-Annotation score: -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).

Pathwayi: starch biosynthesis

This protein is involved in the pathway starch biosynthesis, which is part of Glycan biosynthesis.
