Organism

Campylobacter jejuni subsp. jejuni serotype O:6 (strain 81116 / NCTC 11828) [Complete proteome] [HAMAP]

Taxonomic identifier

407148 [NCBI]

Taxonomic lineage

Bacteria › Proteobacteria › Epsilonproteobacteria › Campylobacterales › Campylobacteraceae › Campylobacter

Protein attributes

Sequence length	200 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	Hydrolyzes non-standard nucleotides such as XTP and dITP/ITP. Might exclude non-standard purines from DNA precursor pool, preventing thus incorporation into DNA and avoiding chromosomal lesions By similarity.
Catalytic activity	NTP + H(2)O = NDP + phosphate.
Cofactor	Divalent cations By similarity.
Subunit structure	Homodimer By similarity.
Sequence similarities	Belongs to the HAM1 NTPase family.
