Protein attributes

Sequence length	131 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

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. HAMAP MF_01624 Arsenate + thioredoxin = arsenite + thioredoxin disulfide + H2O. HAMAP MF_01624
Subunit structure	Monomer By similarity.
Sequence similarities	Belongs to the low molecular weight phosphotyrosine protein phosphatase superfamily. ArsC family.
