CC -!- FUNCTION: Phosphatase that hydrolyzes non-canonical purine nucleotides
CC such as XTP and ITP to their respective diphosphate derivatives.
CC Probably excludes non-canonical purines from DNA/RNA precursor pool,
CC thus preventing their incorporation into DNA/RNA and avoiding
CC chromosomal lesions. {ECO:0000255|HAMAP-Rule:MF_00648}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + XTP = H(+) + phosphate + XDP; Xref=Rhea:RHEA:28406,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:43474,
CC ChEBI:CHEBI:59884, ChEBI:CHEBI:61314; EC=3.6.1.73;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00648};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + ITP = H(+) + IDP + phosphate; Xref=Rhea:RHEA:28330,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:43474,
CC ChEBI:CHEBI:58280, ChEBI:CHEBI:61402; EC=3.6.1.73;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00648};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00648};
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00648};
CC Note=Binds 1 divalent metal cation per subunit; can use either Mg(2+)
CC or Mn(2+). {ECO:0000255|HAMAP-Rule:MF_00648};
CC -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_00648}.
CC -!- SIMILARITY: Belongs to the YjjX NTPase family. {ECO:0000255|HAMAP-
CC Rule:MF_00648}.
