Pisl_1392

Gene
Pisl_1392
Protein
Probable inosine/xanthosine triphosphatase
Organism
Pyrobaculum islandicum (strain DSM 4184 / JCM 9189 / GEO3)
Length
177 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.
