CC -!- FUNCTION: Pyrophosphatase that hydrolyzes non-canonical purine CC nucleotides such as XTP and ITP/dITP to their respective CC monophosphate derivatives. Might exclude non-canonical purines CC from DNA precursor pool, thus preventing their incorporation into CC DNA and avoiding chromosomal lesions. {ECO:0000256|HAMAP- CC Rule:MF_01405}. CC -!- CATALYTIC ACTIVITY: A nucleoside triphosphate + H(2)O = a CC nucleotide + diphosphate. {ECO:0000256|HAMAP-Rule:MF_01405, CC ECO:0000256|SAAS:SAAS00020483}. CC -!- COFACTOR: CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000256|HAMAP- CC Rule:MF_01405}; CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035; Evidence={ECO:0000256|HAMAP- CC Rule:MF_01405}; CC Note=Binds 1 divalent metal cation per subunit; can use either CC Mg(2+) or Mn(2+). {ECO:0000256|HAMAP-Rule:MF_01405}; CC -!- COFACTOR: CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035; CC Evidence={ECO:0000256|SAAS:SAAS00608136}; CC -!- SUBUNIT: Homodimer. {ECO:0000256|HAMAP-Rule:MF_01405, CC ECO:0000256|SAAS:SAAS00020467}. CC -!- SIMILARITY: Belongs to the HAM1 NTPase family. {ECO:0000256|HAMAP- CC Rule:MF_01405, ECO:0000256|RuleBase:RU003781, CC ECO:0000256|SAAS:SAAS00542593}.
