Gene
Shewmr7_3264
Protein
Inosine/xanthosine triphosphatase
Organism
Shewanella sp. (strain MR-7)
Length
179 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.
