plu0558

Gene
plu0558
Protein
Inosine/xanthosine triphosphatase
Organism
Photorhabdus luminescens subsp. laumondii (strain DSM 15139 / CIP 105565 / TT01)
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.
