FIGURE 3.
Arsenic resistance genes in sequenced Exiguobacterium strains Genetic organization of the genes colored by function. arsR arsenical resistance operon repressor; arsD arsenical resistance operon trans-acting repressor; arsA arsenical pump-driving ATPase; Fe–S putative iron sulfur protein; arsB arsenical pump membrane protein; arsC arsenate reductase; acr3 arsenite efflux pump. Heat scale shows identity percentage of all strains sequence, using as reference the Exiguobacterium S17 genes. The first two columns indicate Vishnivetskaya et al. (2009) groupings and 75% ANI clustering, respectively.
