CC -!- FUNCTION: Pyrophosphatase that catalyzes the hydrolysis of CC nucleoside triphosphates to their monophosphate derivatives, with CC a high preference for the non-canonical purine nucleotides XTP CC (xanthosine triphosphate), dITP (deoxyinosine triphosphate) and CC ITP. Seems to function as a house-cleaning enzyme that removes CC non-canonical purine nucleotides from the nucleotide pool, thus CC preventing their incorporation into DNA/RNA and avoiding CC chromosomal lesions. {ECO:0000256|HAMAP-Rule:MF_01405}. CC -!- CATALYTIC ACTIVITY: ITP + H(2)O = IMP + diphosphate. CC {ECO:0000256|HAMAP-Rule:MF_01405}. CC -!- CATALYTIC ACTIVITY: XTP + H(2)O = XMP + diphosphate. CC {ECO:0000256|HAMAP-Rule:MF_01405}. CC -!- CATALYTIC ACTIVITY: dITP + H(2)O = dIMP + diphosphate. CC {ECO:0000256|HAMAP-Rule:MF_01405}. CC -!- COFACTOR: CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000256|HAMAP- CC Rule:MF_01405}; CC Note=Binds 1 Mg(2+) ion per subunit. {ECO:0000256|HAMAP- CC Rule:MF_01405}; CC -!- SUBUNIT: Homodimer. {ECO:0000256|HAMAP-Rule:MF_01405}. CC -!- SIMILARITY: Belongs to the HAM1 NTPase family. {ECO:0000256|HAMAP- CC Rule:MF_01405, ECO:0000256|RuleBase:RU003781}. CC -!- CAUTION: The sequence shown here is derived from an CC EMBL/GenBank/DDBJ whole genome shotgun (WGS) entry which is CC preliminary data. {ECO:0000313|EMBL:EES40348.1}.
