CC -!- FUNCTION: Pyrophosphatase that hydrolyzes the non-canonical purine CC (dITP) as well as 2'-deoxy-N-6-hydroxylaminopurine triphosphate CC (dHAPTP) and 5-bromodeoxyuridine 5'-triphosphate (BrdUTP) to their CC respective monophosphate derivatives. Xanthosine 5'-triphosphate (XTP) CC is also a potential substrate. The enzyme does not distinguish between CC the deoxy- and ribose forms. Probably excludes non-canonical purines CC from RNA and DNA precursor pools, thus preventing their incorporation CC into RNA and DNA and avoiding chromosomal lesions. {ECO:0000256|HAMAP- CC Rule:MF_03148}.
