CC   -!- FUNCTION: Acts on tyrosine phosphorylated proteins, low-MW aryl
CC       phosphates and natural and synthetic acyl phosphates. May be involved
CC       in the regulation of sulfur amino acid metabolism.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=H2O + O-phospho-L-tyrosyl-[protein] = L-tyrosyl-[protein] +
CC         phosphate; Xref=Rhea:RHEA:10684, Rhea:RHEA-COMP:10136, Rhea:RHEA-

CC         ChEBI:CHEBI:82620; EC=3.1.3.48;
CC   -!- SIMILARITY: Belongs to the low molecular weight phosphotyrosine protein
CC       phosphatase family. {ECO:0000305}.
