The ars operon consists of a group of genes coding for a transmembrane pump and an arsenate reductase ( arsC ). The operon includes a regulatory gene ( arsR ) and a gene coding for an arsenite-specific pump ( arsB ) as well as arsC [ 13 ] . Arsenite is pumped directly out of the cell by the arsB protein; however arsenate must first be reduced to arsenite by the cytoplasmic arsenate reductase coded from arsC . Some bacteria also possess other ars genes: arsA produces an arsenite-stimulated ATPase [ 14 ] that results in more efficient arsenite extrusion; arsD encodes for a regulatory protein that controls the upper level of ars expression [ 15 ] ; arsH has been identified but has an uncertain function [ 16 ] .
