Sucrose-phosphatase

From Wikipedia, the free encyclopedia

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.
