CC   -!- FUNCTION: Catalyzes the reversible transfer of the terminal phosphate
CC       of ATP to form a long-chain polyphosphate (polyP). {ECO:0000255|HAMAP-
CC       Rule:MF_00347}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=[phosphate](n) + ATP = [phosphate](n+1) + ADP;
CC         Xref=Rhea:RHEA:19573, Rhea:RHEA-COMP:9859, Rhea:RHEA-COMP:14280,
CC         ChEBI:CHEBI:16838, ChEBI:CHEBI:30616, ChEBI:CHEBI:456216; EC=2.7.4.1;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00347};
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00347};
CC   -!- PTM: An intermediate of this reaction is the autophosphorylated ppk in
CC       which a phosphate is covalently linked to a histidine residue through a
CC       N-P bond. {ECO:0000255|HAMAP-Rule:MF_00347}.
CC   -!- SIMILARITY: Belongs to the polyphosphate kinase 1 (PPK1) family.
CC       {ECO:0000255|HAMAP-Rule:MF_00347}.
