CC   -!- FUNCTION: Pyrophosphatase that catalyzes the hydrolysis of nucleoside
CC       triphosphates to their monophosphate derivatives, with a high
CC       preference for the non-canonical purine nucleotides XTP (xanthosine
CC       triphosphate), dITP (deoxyinosine triphosphate) and ITP. Seems to
CC       function as a house-cleaning enzyme that removes non-canonical purine
CC       nucleotides from the nucleotide pool, thus preventing their
CC       incorporation into DNA/RNA and avoiding chromosomal lesions.
