[[https://www.uniprot.org/uniprot/NTPA_PYRHO NTPA_PYRHO]] Pyrophosphatase that hydrolyzes non-canonical purine nucleotides such as XTP and ITP/dITP to their respective monophosphate derivatives. Might exclude non-canonical purines from DNA precursor pool, thus preventing their incorporation into DNA and avoiding chromosomal lesions (Probable).<ref>PMID:18062990</ref>
[https://www.uniprot.org/uniprot/IXTPA_PYRHO IXTPA_PYRHO] Pyrophosphatase that catalyzes the hydrolysis of nucleoside triphosphates to their monophosphate derivatives, with a high preference for the non-canonical purine nucleotides XTP (xanthosine triphosphate), dITP (deoxyinosine triphosphate) and ITP. Seems to function as a house-cleaning enzyme that removes non-canonical purine nucleotides from the nucleotide pool, thus preventing their incorporation into DNA/RNA and avoiding chromosomal lesions.[HAMAP-Rule:MF_01405]<ref>PMID:18062990</ref>
