[[http://www.uniprot.org/uniprot/PPK_ECOLI PPK_ECOLI]] Catalyzes the reversible transfer of the terminal phosphate of ATP to form a long-chain polyphosphate (polyP). Can form linear polymers of orthophosphate with chain lengths up to 1000 or more. Can also act in the reverse direction to form ATP in the presence of excess ADP. Can also use GTP instead of ATP; but the efficiency of GTP is 5% that of ATP.<ref>PMID:8962061</ref>

[https://www.uniprot.org/uniprot/PPK1_ECOLI PPK1_ECOLI] Catalyzes the reversible transfer of the terminal phosphate of ATP to form a long-chain polyphosphate (polyP). Can form linear polymers of orthophosphate with chain lengths up to 1000 or more. Can use GTP instead of ATP, but the efficiency of GTP is 5% that of ATP. Also exhibits several other enzymatic activities, which include: ATP synthesis from polyP in the presence of excess ADP, general nucleoside-diphosphate kinase activity, linear guanosine 5'-tetraphosphate (ppppG) synthesis and autophosphorylation.<ref>PMID:10660553</ref> <ref>PMID:8962061</ref>
