UniProtKB - Q87DG2 (IXTPA_XYLFT)
Protein
dITP/XTP pyrophosphatase
Gene
PD_0723
Organism
Xylella fastidiosa (strain Temecula1 / ATCC 700964)
Status
Functioni
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.UniRule annotation
