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