Accepted name: ATP-polyphosphate phosphotransferase
Reaction: ATP + (phosphate)n = ADP + (phosphate)n+1
Other name(s): polyphosphate kinase 1; ppk1 (gene name); polyphosphate kinase (ambiguous); polyphosphoric acid kinase (ambiguous)
Systematic name: ATP:polyphosphate phosphotransferase
Comments: The enzyme is responsible for the synthesis of most of the cellular polyphosphate, using the terminal phosphate of ATP as substrate.
