ENZYME entry: EC 3.1.3.24

Accepted Name
Sucrose-phosphate phosphatase.
Alternative Name(s)
SPP.
Sucrose phosphatase.
Sucrose-6-phosphate phosphatase.
Reaction catalysed
Sucrose 6(F)-phosphate + H(2)O <=> sucrose + phosphate
Cofactor(s)
Mg(2+).
Comment(s)
  • This is the final step in the sucrose-biosynthesis pathway.
  • Highly specific for sucrose 6-phosphate, with fructose 6-phosphate unable to act as a substrate.
  • The F in sucrose 6(F)-phosphate is used to indicate that the fructose residue of sucrose carries the substituent.
