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, granule-bound. HAMAP-Rule MF_00484

Tissue specificity

In leaves, flowers and fruits. Observed in all floral whorls at early developmental stages, but restricted to carpel before anthesis.

Induction

Expressed with a circadian rhythm with peak expression at the end of the day. HAMAP-Rule MF_00484

Sequence similarities

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