Protein attributes

Sequence length	141 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

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.
Catalytic activity	Arsenate + glutaredoxin = arsenite + glutaredoxin disulfide + H2O.
Sequence similarities	Belongs to the arsC family.
