OB2237

Gene
OB2237
Protein
Probable inosine/xanthosine triphosphatase
Organism
Oceanobacillus iheyensis (strain DSM 14371 / CIP 107618 / JCM 11309 / KCTC 3954 / HTE831)
Length
170 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.
Mass
