ENZYME entry: EC 3.1.3.25

Accepted Name
Inositol-phosphate phosphatase.
Alternative Name(s)
Inositol 1-phosphatase.
Inositol monophosphate phosphatase.
Inositol phosphatase.
Inositol-1(or 4)-monophosphatase.
L-myo-inositol-1-phosphate phosphatase.
Myo-inositol 1-phosphatase.
Myo-inositol monophosphatase.
Myo-inositol-1(or 4)-monophosphatase.
Myo-inositol-1(or 4)-phosphate phosphohydrolase.
Myo-inositol-1-phosphatase.
Reaction catalysed
Myo-inositol phosphate + H(2)O <=> myo-inositol + phosphate
Comment(s)
  • Acts on five of the six isomers of myo-inositol phosphate, all except myo-inositol 2-phosphate, but does not act on myo-inositol bearing more than one phosphate group.
  • It also acts on adenosine 2'-phosphate (but not the 3'- or 5'-phosphates), sn-glycerol 3-phosphate and glycerol 2-phosphate, but does not act on inositol bisphosphates or more phosphorylated inositols.
