Antimonite (Sb(III)) and antimonate (Sb(V)) are two most frequently detected Sb species in aquatic environment [5] and Sb(V) is 10 times less toxic compared with Sb(III) [6]. The removal of Sb(III) from water is complicated by its weak affinity for coagulants and absorbents resulting from its neutrality over a wide range of pH (2–10.4) [7].
Comamonas testosteroni antA encodes an antimonite
Here we describe a novel bacterial P 1B-type antimonite (Sb(III))-translocating ATPase from the antimony-mining bacterium Comamonas testosterone JL40 that confers resistance to Sb(III). In a comparative proteomics analysis of strain JL40, an operon (ant operon) was up-regulated by Sb(III). The ant operon includes three genes, …
