Chain A,B   (Q9KQ39_VIBCH | Q9KQ39)
molecular function
    GO:0008794    arsenate reductase (glutaredoxin) activity    Catalysis of the reaction: arsenate + reduced glutaredoxin = arsenite + oxidized glutaredoxin. Glutaredoxin functions as the electron donor for arsenate reduction. The electron flow therefore is ( NADPH -> glutathione reductase (EC:1.6.4.2) -> ) glutathione -> glutaredoxin -> arsenate reductase, i.e. glutathione is reduced by glutathione reductase and glutaredoxin is reduced by glutathione.
    GO:0016491    oxidoreductase activity    Catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered. One substrate acts as a hydrogen or electron donor and becomes oxidized, while the other acts as hydrogen or electron acceptor and becomes reduced.
biological process
    GO:0055114    oxidation-reduction process    A metabolic process that results in the removal or addition of one or more electrons to or from a substance, with or without the concomitant removal or addition of a proton or protons.
    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.
