General annotation (Comments)

Function

May contribute to the deposition of transient starch in chloroplasts of leaves.

Catalytic activity

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

Pathway

Glycan biosynthesis; starch biosynthesis.

Subcellular location

Plastid › amyloplast. Plastid › chloroplast. Note: Amyloplast or chloroplast, granule-bound and soluble. Ref.4

Tissue specificity

Expressed in leaves and weakly in endosperm and roots. Ref.4

Developmental stage

Expressed in developing caryopsis at 1 to 5 days after flowering. Expressed exclusively in the pericarp at 5 days after flowering.

Sequence similarities

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

Sequence caution

The sequence BAD15539.1 differs from that shown. Reason: Erroneous gene model prediction.

The sequence BAD16123.1 differs from that shown. Reason: Erroneous gene model prediction.
