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}.
