enzyme is involved in polyphosphate synthesis. The polyphosphate kinase gene is transcribed from a sigma(E) dependent promoter, which could be responsive to environmental stresses |
| 2.7.4.1 | ADP + (phosphate)n+1 |
polyphosphate kinase directly or indirectly regulates DNA polymerase activity or fidelity |
| 2.7.4.1 | ADP + (phosphate)n+1 |
the enzyme protects Salmonella enterica from weak organic acid stress. Polyphosphate may acts as a chemical chaperone that helps refold homoserine transsuccinylase and/or may stimulate proteolysis of toxic denatured protein. The instability of homoserine transsuccinylase may provide a metabolic fuse that blocks growth under conditions that denature proteins. The sensitivity of this fuse is modulated by polyphosphate |
| 2.7.4.1 | ADP + (phosphate)n+1 |
polyphosphate kinases (PPKs) catalyzes the polyP formation or ATP formation, to store energy or to regenerate ATP, respectively |
| 2.7.4.1 | ADP + (phosphate)n+1 |
when Ppk1 from Myxococcus xanthus is incubated with 0.2 mM polyP60-70 and 1 mM ATP or ADP, the rate of ATP synthesis is approximately 1.5-fold higher than that of polyP synthesis. If in the same reaction the proportion of ADP in the ATP/ADP mixture exceeds one-third, the equilibrium shifts to ATP synthesis, suggesting that the enzyme preferentially catalyzed ATP formation |

| 2.7.4.1 | ATP + (phosphate)n |
polyphosphate kinase may be involved in nucleotide metabolism |
| 2.7.4.1 | ATP + (phosphate)n |
involved in phosphate metabolism of bacteria |
