YG5714_0048

Gene
YG5714_0048
Protein
Probable inosine/xanthosine triphosphatase
Organism
Sulfolobus islandicus (strain Y.G.57.14 / Yellowstone #1)
Length
176 amino acids
Function
Phosphatase that hydrolyzes non-canonical purine nucleotides such as XTP and ITP to their respective diphosphate derivatives. Probably excludes non-canonical purines from DNA/RNA precursor pool, thus preventing their incorporation into DNA/RNA and avoiding chromosomal lesions.
Similarity
Belongs to the YjjX NTPase family.
