FIG. 2.
Genomic map (A) and phylogenetic analysis (B) of the arsenate respiratory reductase of SLAS-1T. (A) The arr gene cluster contains at least three genes arranged as arrABD, with likely additional arr genes downstream of arrD. (B) The phylogenetic analysis was performed by using previously established computation methods and representative members of the arsenate respiratory reductase clade of the dimethyl sulfoxide reductase family of molybdenum-containing enzymes (32). An asterisk indicates that the organism is known to respire arsenate. GenBank accession numbers are indicated in parentheses. The second numbers in parentheses for A. ehrlichii are gene identification numbers within the genome sequence.
