CC   -!- FUNCTION: Involved in the biosynthesis of ADP-glucose, a building block
CC       required for the elongation reactions to produce glycogen. Catalyzes
CC       the reaction between ATP and alpha-D-glucose 1-phosphate (G1P) to
CC       produce pyrophosphate and ADP-Glc. {ECO:0000255|HAMAP-Rule:MF_00624}.
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; Evidence={ECO:0000255|HAMAP-
CC         Rule:MF_00624};
CC   -!- PATHWAY: Glycan biosynthesis; glycogen biosynthesis.
CC       {ECO:0000255|HAMAP-Rule:MF_00624}.
CC   -!- SUBUNIT: Homotetramer. {ECO:0000255|HAMAP-Rule:MF_00624}.
CC   -!- SIMILARITY: Belongs to the bacterial/plant glucose-1-phosphate
CC       adenylyltransferase family. {ECO:0000255|HAMAP-Rule:MF_00624}.
