Abstract

Bacterial arsenic resistance (ars) operons encode an arsenite-efflux system that can be a secondary carrier protein (ArsB) or an anion-translocating ATPase (ArsAB). Yeasts extrude arsenite using Acr3p, a plasma membrane carrier protein, or sequester it in vacuoles as the glutathione conjugate using Ycf1p, an ABC transporter.
