Organism

Caulobacter crescentus (Caulobacter vibrioides) [Complete proteome] [HAMAP]

Taxonomic identifier

155892 [NCBI]

Taxonomic lineage

Bacteria › Proteobacteria › Alphaproteobacteria › Caulobacterales › Caulobacteraceae › Caulobacter

Protein attributes

Sequence length	194 AA.
Sequence status	Complete.
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. HAMAP MF_01405
Catalytic activity	NTP + H2O = NDP + phosphate. HAMAP MF_01405
Cofactor	Divalent cations By similarity. HAMAP MF_01405
Subunit structure	Homodimer By similarity. HAMAP MF_01405
Sequence similarities	Belongs to the HAM1 NTPase family.
