Chain A   (ARSA1_ECOLX | P08690)
molecular function
    GO:0005524    ATP binding    Interacting selectively and non-covalently with ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
    GO:0016887    ATPase activity    Catalysis of the reaction: ATP + H2O = ADP + phosphate + 2 H+. May or may not be coupled to another reaction.
    GO:0015446    ATPase-coupled arsenite transmembrane transporter activity    Catalysis of the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: ATP + H2O + arsenite(in) = ADP + phosphate + arsenite(out).
    GO:0016787    hydrolase activity    Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3.
    GO:0000166    nucleotide binding    Interacting selectively and non-covalently with a nucleotide, any compound consisting of a nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the ribose or deoxyribose.
biological process
    GO:0098656    anion transmembrane transport    A process in which an anion is transported from one side of a membrane to the other by means of some agent such as a transporter or pore.
    GO:0098655    cation transmembrane transport    A process in which a cation is transported from one side of a membrane to the other by means of some agent such as a transporter or pore.
    GO:0071722    detoxification of arsenic-containing substance    Any process that reduces or removes the toxicity of compounds containing arsenic, including arsenates, arsenites, and arsenides. These include transport of such compounds away from sensitive areas and to compartments or complexes whose purpose is sequestration of arsenic or arsenic-containing compounds.
    GO:0046685    response to arsenic-containing substance    Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an arsenic stimulus from compounds containing arsenic, including arsenates, arsenites, and arsenides.
