OC Bacteria; Proteobacteria; Gammaproteobacteria; Alteromonadales; OC Alteromonadaceae; Glaciecola. OX NCBI_TaxID=1129793; RN [1] RP NUCLEOTIDE SEQUENCE. RC STRAIN=LMG 21857; RA Qin Q.L., Xie B.B., Shu Y.L., Zhang Y.Z.; RT "Genome Sequencing of Glaciecola polaris LMG 21857."; RL Submitted (JAN-2012) 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 (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.
