4-nitrophenyl phosphate + H2O 4-nitrophenol + phosphate

This enzyme belongs to the family of hydrolases, specifically those acting on phosphoric monoester bonds. The systematic name of this enzyme class is 4-nitrophenylphosphate phosphohydrolase. Other names in common use include nitrophenyl phosphatase, p-nitrophenylphosphatase, para-nitrophenyl phosphatase, K-pNPPase, NPPase, PNPPase, Ecto-p-nitrophenyl phosphatase, and p-nitrophenylphosphate phosphohydrolase. This enzyme participates in γ-hexachlorocyclohexane degradation.
