7.3.2.7 additional information the ArsA protein is a membrane associated ATPase, energizing the arsenite efflux pump by ATP hydrolysis, ArsA is attached to the ArsB inner-membrane protein. The ArsB protein can function alone as a chemiosmotic, membrane-potential driven arsenite-efflux transporter or together with ArsA as an ATP-driven primary membrane pump. ArsC converts the less toxic arsenate to more toxic arsenite, the substrate for the ArsB transport protein Escherichia coli ?
