Protein

Non-canonical purine NTP pyrophosphatase

Gene

Npun_R4467

Organism
Nostoc punctiforme (strain ATCC 29133 / PCC 73102)
Status
Unreviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

Functioni

Pyrophosphatase that hydrolyzes non-canonical purine nucleotides such as XTP and ITP/dITP to their respective monophosphate derivatives. Might exclude non-canonical purines from DNA precursor pool, thus preventing their incorporation into DNA and avoiding chromosomal lesions.UniRule annotation

Catalytic activityi

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

Cofactori

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