Description

Members of the ACR3 family of arsenite (As(III)) permeases confer resistance to arsenic by extrusion from cells
[8]
. They exist in prokaryotes and eukaryotes (lower plants and fungi)
[7, 4]
. The ACR3 permeases have ten-transmembrane span topology
[5]
. Corynebacterium glutamicum has three Acr3 proteins, CgAcr3-1, CgAcr3-2, and CgAcr3-3. CgAcr3-1 is thought to be an antiporter that catalyses arsenite-proton exchange
[9]
.

The Shewanella oneidensis Acr3 is not able to transport As(III) and confers resistance only to arsenate (As(V))
[2]
, whereas the Acr3 orthologue from Synechocystis mediates tolerance to As(III), As(V) and antimonite (Sb(III))
[3]
.

In budding yeast, overexpression of the Acr3 gene confers an arsenite- but not an arsenate-resistance phenotype
[1]
. Saccharomyces cerevisiae Acr3 is a plasma membrane metalloid/H+ antiporter that transports arsenite and antimonite
[6]
.
