Protein

Non-canonical purine NTP pyrophosphatase

Gene

NMB0639

Organism
Neisseria meningitidis serogroup B (strain MC58)
Status
Reviewed-Annotation score: 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 annotation

Cofactori

Mg2+UniRule annotation, Mn2+UniRule annotationNote: Binds 1 divalent metal cation per subunit; can use either Mg2+ or Mn2+.UniRule annotation

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
