FUNCTION: Reduces arsenate [As(V)] to arsenite [As(III)] and dephosphorylates tyrosine phosphorylated proteins, low-MW aryl phosphates and natural and synthetic acyl phosphates. Could switch between different functions in different circumstances (By similarity).
CATALYTIC ACTIVITY: Protein tyrosine phosphate + H₂O = protein tyrosine + phosphate.
CATALYTIC ACTIVITY: Arsenate + thioredoxin = arsenite + thioredoxin disulfide + H₂O.
SUBUNIT: Monomer (By similarity).
SIMILARITY: Belongs to the low molecular weight phosphotyrosine protein phosphatase superfamily. ArsC family.
