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.
