Functional Description

 Pyrophosphatase that hydrolyzes the non-canonical purine nucleotides deoxyinosine triphosphate (dITP) and xanthosine triphosphate (XTP) as well as 2'-deoxy-N-6-hydroxylaminopurine triposphate (dHAPTP) to their respective monophosphate derivatives. Probably excludes non-canonical purines from DNA precursor pool, thus preventing their incorporation into DNA and avoiding chromosomal lesions (By similarity).
