Taxonomic lineage

Bacteria › Proteobacteria › Alphaproteobacteria › Rhizobiales › Rhizobiaceae › Rhizobium/Agrobacterium group › Agrobacterium

Protein attributes

Sequence length	177 AA.
Sequence status	Complete.
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 HAMAP MF_00209.
Sequence similarities	Belongs to the PPase family.
