Protein

Inosine triphosphate pyrophosphatase

Gene

ECU04_1180

Organism
Encephalitozoon cuniculi (strain GB-M1) (Microsporidian parasite)
Status
Reviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

Functioni

Pyrophosphatase that hydrolyzes non-canonical purine nucleotides such as inosine triphosphate (ITP), deoxyinosine triphosphate (dITP) or xanthosine 5'-triphosphate (XTP) to their respective monophosphate derivatives. The enzyme does not distinguish between the deoxy- and ribose forms. Probably excludes non-canonical purines from RNA and DNA precursor pools, thus preventing their incorporation into RNA and DNA and avoiding chromosomal lesions.UniRule annotation

Catalytic activityi

A nucleoside triphosphate + H2O = a nucleotide + diphosphate.UniRule annotation

Cofactori

Binds 1 divalent metal cation ion per subunit; can use either magnesium or manganese.UniRule annotation
