OC Bacteria; Proteobacteria; Alphaproteobacteria; Rhizobiales; OC Bartonellaceae; Bartonella. OX NCBI_TaxID=1094492; RN [1] RP NUCLEOTIDE SEQUENCE. RC STRAIN=M02; RX PubMed=23555299; DOI=10.1371/journal.pgen.1003393; RA Guy L., Nystedt B., Toft C., Zaremba-Niedzwiedzka K., Berglund E.C., RA Granberg F., Naslund K., Eriksson A.S., Andersson S.G.; RT "A gene transfer agent and a dynamic repertoire of secretion systems RT hold the keys to the explosive radiation of the emerging pathogen RT Bartonella."; RL PLoS Genet. 9:E1003393-E1003393(2013). CC -!- FUNCTION: Pyrophosphatase that hydrolyzes non-canonical purine CC nucleotides such as XTP and ITP/dITP to their respective CC monophosphate derivatives. Might exclude non-canonical purines CC from DNA precursor pool, thus preventing their incorporation into CC DNA and avoiding chromosomal lesions (By similarity). CC -!- CATALYTIC ACTIVITY: A nucleoside triphosphate + H(2)O = a CC nucleotide + diphosphate. CC -!- COFACTOR: Binds 1 divalent metal cation ion per subunit; can use CC either magnesium or manganese (By similarity). CC -!- SUBUNIT: Homodimer (By similarity). CC -!- SIMILARITY: Belongs to the HAM1 NTPase family. CC -!- CAUTION: The sequence shown here is derived from an CC EMBL/GenBank/DDBJ whole genome shotgun (WGS) entry which is CC preliminary data.
