ID NTPA_RHORT Reviewed; 201 AA. AC Q2RN61; DT 20-MAY-2008, integrated into UniProtKB/Swiss-Prot. DT 24-JAN-2006, sequence version 1. DT 10-JUN-2008, entry version 19. DE Nucleoside-triphosphatase (EC 3.6.1.15) (Nucleoside triphosphate DE phosphohydrolase) (NTPase). GN OrderedLocusNames=Rru_A3640; OS Rhodospirillum rubrum (strain ATCC 11170 / NCIB 8255). OC Bacteria; Proteobacteria; Alphaproteobacteria; Rhodospirillales; OC Rhodospirillaceae; Rhodospirillum. OX NCBI_TaxID=269796; RN [1] RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RA Copeland A., Lucas S., Lapidus A., Barry K., Detter J.C., Glavina T., RA Hammon N., Israni S., Pitluck S., Munk A.C., Brettin T., Bruce D., RA Han C., Tapia R., Gilna P., Schmutz J., Larimer F., Land M., RA Kyrpides N., Mavrommatis K., Richardson P., Zhang Y., Roberts G., RA Reslewic S., Zhou S., Schwartz D.C.; RT "Complete sequence of the chromosome of Rhodospirillum rubrum ATCC RT 11170."; RL Submitted (DEC-2005) to the EMBL/GenBank/DDBJ databases. CC -!- FUNCTION: Hydrolyzes non-standard nucleotides such as XTP and CC dITP/ITP. Might exclude non-standard purines from DNA precursor CC pool, preventing thus incorporation into DNA and avoiding CC chromosomal lesions (By similarity). CC -!- CATALYTIC ACTIVITY: NTP + H(2)O = NDP + phosphate. CC -!- COFACTOR: Divalent cations (By similarity). CC -!- SUBUNIT: Homodimer (By similarity). CC -!- SIMILARITY: Belongs to the HAM1 NTPase family.
