Polyphosphate Polymerase/YidH (PoPo) Superfamily

Full length polyphosphate polymerases (TC# 4.E.1) have a C-terminal 3 TMS domain that is in the ubiquitous DUF202 domain/E. coli YidH protein Family (TC# 9.B.51). These small proteins, all with 3 TMSs, are found in bacteria, archaea and eukaryotes.

4.E.1 - The Vacuolar (Acidocalcisome) Polyphosphate Polymerase (V-PPP) Family
9.B.51 - The Uncharacterized DUF202/YidH (YidH) Family
