Thus, the two substrates of this enzyme are 4-nitrophenyl phosphate and H2O, whereas its two products are 4-nitrophenol and 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 gamma-hexachlorocyclohexane degradation.
Structural studies
As of late 2007, only one structure has been solved for this class of enzymes, with the PDB accession code PDB: 1VJR.
