Reaction: [a protein]-tyrosine phosphate + H2O = [a protein]-tyrosine + phosphate
Other name(s): phosphotyrosine phosphatase; phosphoprotein phosphatase (phosphotyrosine); phosphotyrosine histone phosphatase; protein phosphotyrosine phosphatase; tyrosylprotein phosphatase; phosphotyrosine protein phosphatase; phosphotyrosylprotein phosphatase; tyrosine O-phosphate phosphatase; PPT-phosphatase; PTPase; [phosphotyrosine]protein phosphatase; PTP-phosphatase
Systematic name: protein-tyrosine-phosphate phosphohydrolase
Comments: Dephosphorylates O-phosphotyrosine groups in phosphoproteins, such as the products of EC EC 126.96.36.199 non-specific protein-tyrosine kinase.
