ID ARSC_OCEIH Reviewed; 139 AA. AC Q8ENQ5; DT 10-JAN-2006, integrated into UniProtKB/Swiss-Prot. DT 01-MAR-2003, sequence version 1. DT 16-JUN-2009, entry version 36. DE RecName: Full=Protein arsC; DE AltName: Full=Arsenate reductase; DE EC=1.20.4.-; DE AltName: Full=Arsenical pump modifier; DE AltName: Full=Low molecular weight protein-tyrosine-phosphatase; DE EC=3.1.3.48; GN Name=arsC; OrderedLocusNames=OB2423; OS Oceanobacillus iheyensis. OC Bacteria; Firmicutes; Bacillales; Bacillaceae; Oceanobacillus. OX NCBI_TaxID=182710; RN [1] RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RC STRAIN=DSM 14371 / JCM 11309 / KCTC 3954 / HTE831; RX MEDLINE=22220767; PubMed=12235376; DOI=10.1093/nar/gkf526; RA Takami H., Takaki Y., Uchiyama I.; RT "Genome sequence of Oceanobacillus iheyensis isolated from the Iheya RT Ridge and its unexpected adaptive capabilities to extreme RT environments."; RL Nucleic Acids Res. 30:3927-3935(2002). CC -!- FUNCTION: Reduces arsenate [As(V)] to arsenite [As(III)] and CC dephosphorylates tyrosine phosphorylated proteins, low-MW aryl CC phosphates and natural and synthetic acyl phosphates. Could switch CC between different functions in different circumstances (By CC similarity). CC -!- CATALYTIC ACTIVITY: Protein tyrosine phosphate + H(2)O = protein CC tyrosine + phosphate. CC -!- CATALYTIC ACTIVITY: Arsenate + thioredoxin = arsenite + CC thioredoxin disulfide + H(2)O. CC -!- SUBUNIT: Monomer (By similarity). CC -!- SIMILARITY: Belongs to the low molecular weight phosphotyrosine CC protein phosphatase superfamily. ArsC family.
