Inositol-1,4-bisphosphate 1-phosphatase
- Inositol-1,4-bisphosphate 1-phosphatase
In enzymology, an inositol-1,4-bisphosphate 1-phosphatase (EC number|3.1.3.57) is an enzyme that catalyzes the chemical reaction
:1D-myo-inositol 1,4-bisphosphate + H2O 1D-myo-inositol 4-phosphate + phosphate
Thus, the two substrates of this enzyme are 1D-myo-inositol 1,4-bisphosphate and H2O, whereas its two products are 1D-myo-inositol 4-phosphate 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 1D-myo-inositol-1,4-bisphosphate 1-phosphohydrolase. This enzyme is also called inositol-polyphosphate 1-phosphatase. This enzyme participates in inositol phosphate metabolism and phosphatidylinositol signaling system.
