PF03976 | Polyphosphate kinase 2 (PPK2) (PPK2) | Polyphosphate kinase 2 (PPK2) | Inorganic polyphosphate (polyP) plays a role in metabolism and regulation and has been proposed to serve as a energy source in a pre-ATP world. In prokaryotes, the synthesis and utilisation of polyP are catalysed by PPK1, PPK2 and polyphosphatases. ... | Domain |
