Protein attributes

Sequence length	181 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

Catalytic activity	Diphosphate + H2O = 2 phosphate. HAMAP MF_00209
Cofactor	Binds 4 magnesium ions per subunit. Other metal ions can support activity, but at a lower rate. Two magnesium ions are required for the activation of the enzyme and are present before substrate binds, two additional magnesium ions form complexes with substrate and product By similarity.
Subcellular location	Cytoplasm By similarity.
Sequence similarities	Belongs to the PPase family.
