The ArsR repressor mediates arsenite-dependent regulation of arsenate respiration and detoxification operons of Shewanella sp. strain ANA-3.

Journal of bacteriology - 1 Nov 2009

Murphy Julie N, Saltikov Chad W

Abstract excerpt

Microbial arsenate reduction affects the fate and transport of arsenic in the environment. Arsenate respiratory (arr) and detoxifying (ars) reduction pathways in Shewanella sp. strain ANA-3 are induced by arsenite and under anaerobic conditions. Here it is shown that an ArsR family protein, called ArsR2, regulates the arsenate respiratory reduction pathway in response to elevated arsenite under anaerobic...
