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:0000269|PubMed:1648099}.
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         Evidence={ECO:0000269|PubMed:1648099};
CC   -!- ACTIVITY REGULATION: Allosterically activated by fructose-1,6-
CC       bisphosphate (F16BP), hexanediol 1,6-bisphosphate, NADPH and pyridoxal
CC       phosphate. Inhibited by AMP and by high concentrations of MgCl(2).
CC       {ECO:0000269|PubMed:1648099, ECO:0000269|PubMed:2162151,
CC       ECO:0000269|PubMed:21741429}.
CC   -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC       Kinetic parameters:
CC         KM=25 uM for alpha-D-glucose 1-phosphate
CC         {ECO:0000269|PubMed:1648099};
CC         KM=120 uM for diphosphate {ECO:0000269|PubMed:1648099};
CC         Vmax=133 umol/min/mg enzyme toward alpha-D-glucose 1-phosphate
CC         {ECO:0000269|PubMed:1648099};
CC         Vmax=97 umol/min/mg enzyme toward diphosphate
CC         {ECO:0000269|PubMed:1648099};
CC         Note=kcat is 111 sec(-1) for adenylyltransferase activity. kcat is 81
CC         sec(-1) for pyrophosphorylase activity. {ECO:0000269|PubMed:1648099};
CC   -!- PATHWAY: Glycan biosynthesis; glycogen biosynthesis. {ECO:0000305}.
CC   -!- SUBUNIT: Homotetramer; dimer of dimers. {ECO:0000269|PubMed:27545622,
CC       ECO:0000269|PubMed:826540}.
CC   -!- INDUCTION: mRNA stability is at least partially under the control of
CC       CsrA; loss of csrA leads to higher transcript levels, possibly mediated
CC       by protein binding to the mRNA (PubMed:7751274).
CC       {ECO:0000269|PubMed:7751274}.
CC   -!- MISCELLANEOUS: Displays cooperative behavior and a bibi mechanism with
CC       sequential binding of ATP and G1P, followed by ordered release of
CC       pyrophosphate and ADP-Glc. {ECO:0000269|PubMed:27545622}.
CC   -!- SIMILARITY: Belongs to the bacterial/plant glucose-1-phosphate
CC       adenylyltransferase family. {ECO:0000305}.
