Identification
Name:Polyphosphate kinase
Synonyms:
  • ATP-polyphosphate phosphotransferase
  • Polyphosphoric acid kinase
Gene Name:ppk
Enzyme Class:
Biological Properties
General Function:Involved in catalytic activity
Specific Function: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
Cellular Location:Cell inner membrane; Peripheral membrane protein
