In enzymology, an inositol-phosphate phosphatase (EC 3.1.3.25) is an enzyme that catalyzes the chemical reaction

myo-inositol phosphate + H2O \rightleftharpoons myo-inositol + phosphate

Thus, the two substrates of this enzyme are myo-inositol phosphate and H2O, whereas its two products are myo-inositol and phosphate.

This enzyme participates in 3 metabolic pathways: streptomycin biosynthesis, inositol phosphate metabolism, and phosphatidylinositol signaling system.

Nomenclature[edit]

This enzyme belongs to the family of hydrolases, specifically those acting on phosphoric monoester bonds. The systematic name of this enzyme class is myo-inositol-phosphate phosphohydrolase. Other names in common use include:

  • myo-inositol-1(or 4)-monophosphatase,
  • inositol 1-phosphatase,
  • L-myo-inositol-1-phosphate phosphatase,
  • myo-inositol 1-phosphatase,
  • inositol phosphatase,
  • inositol monophosphate phosphatase,
  • inositol-1(or 4)-monophosphatase,
  • myo-inositol-1(or 4)-phosphate phosphohydrolase,
  • myo-inositol monophosphatase, and
  • myo-inositol-1-phosphatase.
