Taxonomic identifier

354242 [NCBI]

Taxonomic lineage

Bacteria › Proteobacteria › Epsilonproteobacteria › Campylobacterales › Campylobacteraceae › Campylobacter

Protein attributes

Sequence length	200 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	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 By similarity. HAMAP MF_01405
Catalytic activity	A nucleoside triphosphate + H2O = a nucleotide + diphosphate. HAMAP MF_01405
Cofactor	Binds 1 divalent metal cation ion per subunit; can use either magnesium or manganese By similarity.
Subunit structure	Homodimer By similarity. HAMAP MF_01405
Sequence similarities	Belongs to the HAM1 NTPase family.
