Mannitol 1 phosphatase

In enzymology, a mannitol-1-phosphatase (EC 3.1.3.22) is an enzyme that catalyzes the chemical reaction

Thus, the two substrates of this enzyme are D-mannitol 1-phosphate and H₂O, whereas its two products are D-mannitol 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 D-mannitol-1-phosphate phosphohydrolase. This enzyme is also called mannitol-1-phosphate phosphatase. This enzyme participates in fructose and mannose metabolism.
