CC   -!- FUNCTION: Dephosphorylates etk.
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}.
CC   -!- CAUTION: In E.coli K12 / MG1655 and K12 / W3110 this operon is silenced
CC       by an IS1D insertion in the promoter region. {ECO:0000305}.
