CC -!- FUNCTION: This protein plays a role in synthesis of starch. It
CC catalyzes the synthesis of the activated glycosyl donor, ADP-glucose
CC from Glc-1-P and ATP.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=alpha-D-glucose 1-phosphate + ATP + H(+) = ADP-alpha-D-glucose
CC + diphosphate; Xref=Rhea:RHEA:12120, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:30616, ChEBI:CHEBI:33019, ChEBI:CHEBI:57498,
CC ChEBI:CHEBI:58601; EC=2.7.7.27;
CC -!- ACTIVITY REGULATION: Activated by 3'phosphoglycerate, inhibited by
CC orthophosphate. Allosteric regulation.
CC -!- PATHWAY: Glycan biosynthesis; starch biosynthesis.
CC -!- SUBUNIT: Heterotetramer.
CC -!- INTERACTION:
CC P23509; Q00081: AGPS1; NbExp=2; IntAct=EBI-15812097, EBI-15812120;
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast. Plastid, amyloplast.
CC Note=Found in the chloroplast in leaf. Found in the plastid in the
CC developing endosperm.
CC -!- TISSUE SPECIFICITY: Leaves and tubers.
CC -!- SIMILARITY: Belongs to the bacterial/plant glucose-1-phosphate
CC adenylyltransferase family. {ECO:0000305}.
