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.
CC {ECO:0000255|HAMAP-Rule:MF_01405}.
CC -!- CATALYTIC ACTIVITY:
