In enzymology, a sucrose-phosphatase (EC 3.1.3.24) is an enzyme that catalyzes the chemical reaction
- sucrose 6F-phosphate + H2O
sucrose + phosphate
Thus, the two substrates of this enzyme are sucrose 6F-phosphate and H2O, whereas its two products are sucrose 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 sucrose-6F-phosphate phosphohydrolase. Other names in common use include sucrose 6-phosphate hydrolase, sucrose-phosphate hydrolase, sucrose-phosphate phosphohydrolase, and sucrose-6-phosphatase. This enzyme participates in starch and sucrose metabolism.
Structural studies
As of late 2007, 9 structures have been solved for this class of enzymes, with PDB accession codes 1S2O, 1TJ3, 1TJ4, 1TJ5, 1U2S, 1U2T, 2B1Q, 2B1R, and 2D2V.
