CC   -!- FUNCTION: Reduces arsenate [As(V)] to arsenite [As(III)] and
CC       dephosphorylates tyrosine phosphorylated proteins, low-MW aryl
CC       phosphates and natural and synthetic acyl phosphates. Could switch
CC       between different functions in different circumstances (By
CC       similarity).
CC   -!- CATALYTIC ACTIVITY: Protein tyrosine phosphate + H(2)O = protein
CC       tyrosine + phosphate.
CC   -!- CATALYTIC ACTIVITY: Arsenate + thioredoxin = arsenite +
CC       thioredoxin disulfide + H(2)O.
CC   -!- SUBUNIT: Monomer (By similarity).
CC   -!- SIMILARITY: Belongs to the low molecular weight phosphotyrosine
CC       protein phosphatase superfamily. ArsC family.
