Protein
Putative arsenate reductase
Organism
Escherichia coli (strain K12)
Function
Reduction of arsenate [As(V)] to arsenite [As(III)]. This protein expands the substrate specificity of ArsAB pump which can extrude arsenite and antimonite to allow for arsenate pumping and resistance (By similarity).
Similarity
Belongs to the ArsC family.
