CC   -!- FUNCTION: Pyrophosphatase that catalyzes the hydrolysis of
CC       nucleoside triphosphates to their monophosphate derivatives, with
CC       a high preference for the non-canonical purine nucleotides XTP
CC       (xanthosine triphosphate), dITP (deoxyinosine triphosphate) and
CC       ITP. Seems to function as a house-cleaning enzyme that removes
CC       non-canonical purine nucleotides from the nucleotide pool, thus
CC       preventing their incorporation into DNA/RNA and avoiding
CC       chromosomal lesions. {ECO:0000256|HAMAP-Rule:MF_01405,
CC       ECO:0000256|SAAS:SAAS00805977}.
CC   -!- CATALYTIC ACTIVITY: ITP + H(2)O = IMP + diphosphate.
