CC chloroplasts of leaves.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=[(1->4)-alpha-D-glucosyl](n) + ADP-alpha-D-glucose = [(1->4)-
CC alpha-D-glucosyl](n+1) + ADP + H(+); Xref=Rhea:RHEA:18189, Rhea:RHEA-
CC COMP:9584, Rhea:RHEA-COMP:9587, ChEBI:CHEBI:15378, ChEBI:CHEBI:15444,
CC ChEBI:CHEBI:57498, ChEBI:CHEBI:456216; EC=2.4.1.21;
CC -!- PATHWAY: Glycan biosynthesis; starch biosynthesis.
CC -!- SUBCELLULAR LOCATION: Plastid, amyloplast
CC {ECO:0000269|PubMed:15232694}. Plastid, chloroplast
CC {ECO:0000269|PubMed:15232694}. Note=Amyloplast or chloroplast, granule-
CC bound and soluble.
CC -!- TISSUE SPECIFICITY: Expressed in leaves and weakly in endosperm and
CC roots. {ECO:0000269|PubMed:15232694}.
CC -!- DEVELOPMENTAL STAGE: Expressed in developing caryopsis at 1 to 5 days
CC after flowering. Expressed exclusively in the pericarp at 5 days after
CC flowering.
CC -!- SIMILARITY: Belongs to the glycosyltransferase 1 family.
CC Bacterial/plant glycogen synthase subfamily. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
