From: A new family of periplasmic-binding proteins that sense arsenic oxyanions
Phylogeny of arsenic-metabolising bacteria, metabolic enzymes and regulatory proteins. Trees are for 16S rRNA gene (16S); AioX homologues (X); AioS homologues (S); AioR homologues (R); and the molybdenum-containing subunits of Aio, Arx and Arr (Mo). Trees are bootstrap consensus trees constructed using the maximum-likelihood method from 200 resamples and are rooted using the 16S rRNA gene from Sulfolobus tokodaii, and the protein sequences from TorT, TorS, TorR and TorA for X, S, R and Mo, respectively.
