  • Despite the suggestion of HGT and duplication events, the arsC phylogeny suggests that arsenate reductase is an evolutionarily old enzyme, a hypothesis that was recently suggested for arsenite oxidase [ 38 ] . This is the first phylogenetic analysis of an arsenic redox active gene to include all three domains and the Archaea and Bacteria were clearly separated, with S. cerevisiae subsequently branching from Archaea.

  • Inorganic arsenic exists primarily in two valence states: arsenite (As III ) and arsenate (As V , or the arsenate ion AsO 4 3-).

  • Furthermore, arsenite is generally more labile and toxic than arsenate [ 26 ] , so that expression of arsC , and the ensuing reduction of arsenate to arsenite, might increase the toxicity of arsenic in the environment.

  • The arsC gene is of particular interest in that its product, the soluble enzyme arsenate reductase, catalyzes the reduction of arsenate to arsenite.

  • Both forms are toxic to microorganisms, with arsenite disrupting enzyme function, and arsenate behaving as a phosphate analog and interfering with phosphate uptake and utilization [ 1 ] . Microorganisms have evolved a variety of mechanisms for coping with arsenic toxicity, including minimizing the amount of arsenic that enters the cell (e.g.
