OX NCBI_TaxID=1304889 {ECO:0000313|EMBL:KGH42369.1, ECO:0000313|Proteomes:UP000029801}; RN [1] {ECO:0000313|EMBL:KGH42369.1} RP NUCLEOTIDE SEQUENCE. RC STRAIN=CMPG5300 {ECO:0000313|EMBL:KGH42369.1}; RA Malik S., Siezen R.J., Renckens B., Vaneechoutte M., Vanderleyden J., RA Lebeer S.; RT "Draft genome sequence of Lactobacillus plantarum CMPG5300, a human RT isolate."; RL Submitted (OCT-2013) to the EMBL/GenBank/DDBJ databases. 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. {ECO:0000256|HAMAP- CC Rule:MF_01405}. CC -!- CATALYTIC ACTIVITY: A nucleoside triphosphate + H(2)O = a CC nucleotide + diphosphate. {ECO:0000256|HAMAP-Rule:MF_01405}. CC -!- COFACTOR: CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000256|HAMAP- CC Rule:MF_01405}; CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035; Evidence={ECO:0000256|HAMAP- CC Rule:MF_01405}; CC Note=Binds 1 divalent metal cation per subunit; can use either CC Mg(2+) or Mn(2+). {ECO:0000256|HAMAP-Rule:MF_01405}; CC -!- SUBUNIT: Homodimer. {ECO:0000256|HAMAP-Rule:MF_01405}. CC -!- SIMILARITY: Belongs to the HAM1 NTPase family. {ECO:0000256|HAMAP- CC Rule:MF_01405}. CC -!- CAUTION: The sequence shown here is derived from an CC EMBL/GenBank/DDBJ whole genome shotgun (WGS) entry which is CC preliminary data. {ECO:0000313|EMBL:KGH42369.1}.
