Arsenic-resistant bacteria have evolved various efflux systems for arsenic resistance. Five arsenic efflux proteins, ArsB, Acr3, ArsP, ArsJ and MSF1, have been reported. In this study, comprehensive analyses were performed to study the function of a putative major facilitator superfamily gene arsK and the regulation of arsK transcriptional expression in Agrobacterium tumefaciens GW4. We found that (1) arsK is located on an arsenic gene island in strain GW4, ArsK orthologs are widely distributed… CONTINUE READING
