CC -!- FUNCTION: Pyrophosphatase that hydrolyzes non-canonical purine
CC nucleotides such as inosine triphosphate (ITP), deoxyinosine
CC triphosphate (dITP) or xanthosine 5'-triphosphate (XTP) to their
CC respective monophosphate derivatives. The enzyme does not distinguish
CC between the deoxy- and ribose forms. Probably excludes non-canonical
CC purines from RNA and DNA precursor pools, thus preventing their
CC incorporation into RNA and DNA and avoiding chromosomal lesions.
