ENZYME entry: EC 2.7.4.34
Accepted Name |
GDP-polyphosphate phosphotransferase.
|
Alternative Name(s) |
polyphosphate kinase 2. |
Reaction catalysed |
[phosphate](n) + GTP <=> [phosphate](n+1) + GDP |
Comment(s) |
- Polyphosphate kinase 2, characterized from the bacterium Pseudomonas
aeruginosa, uses inorganic polyphosphate as a donor to convert GDP to
GTP.
- The enzyme can also act on ADP (cf. EC 2.7.4.1), but with lower
activity.
- The enzyme has only a trivial activity in the opposite direction
(synthesizing polyphosphate from GTP).
- The GTP that is produced is believed to be consumed by EC 2.7.7.13.
