Phylogenetic tree of inferred amino acid sequences of two different arsenite transporter families: 1 ACR3p; [1.1] ACR3(1)p; [1.2] ACR3(2)p; and 2 ArsB. Numbers at nodes represent bootstrap confidence values obtained with 1000 resamplings; values below 50 are not shown. The GenBank accession numbers for the corresponding arsenate reductase gene sequences are given in parentheses. Bar Substitutions per site
