Protein attributes

Sequence length	204 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Pyrophosphatase that hydrolyzes non-canonical purine nucleotides such as XTP and ITP/dITP to their respective monophosphate derivatives. Might exclude non-canonical purines from DNA precursor pool, thus preventing their incorporation into DNA and avoiding chromosomal lesions By similarity. HAMAP MF_01405
Catalytic activity	A nucleoside triphosphate + H2O = a nucleotide + diphosphate. HAMAP MF_01405 SAAS SAAS020922
Cofactor	Binds 1 divalent metal cation ion per subunit; can use either magnesium or manganese By similarity. HAMAP MF_01405 SAAS SAAS020922
Subunit structure	Homodimer By similarity. HAMAP MF_01405 SAAS SAAS020922
Sequence similarities	Belongs to the HAM1 NTPase family. HAMAP MF_01405
