Novel Pathway for Arsenic Detoxification in the Legume Symbiont Sinorhizobium meliloti
Abstract
We report a novel pathway for arsenic detoxification in the legume symbiont Sinorhizobium meliloti. Although a majority of ars operons consist of three genes, arsR (transcriptional regulator), arsB [As(OH)3/H+ antiporter], and arsC (arsenate reductase), the S. meliloti ars operon includes an aquaglyceroporin (aqpS) in place of arsB. The presence of AqpS in an arsenic resistance operon is interesting, since aquaglyceroporin channels have …
