EC Tree
     3 Hydrolases
         3.1 Acting on ester bonds
             3.1.3 Phosphoric-monoester hydrolases
                3.1.3.25 inositol-phosphate phosphatase
IUBMB Comments
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. Two isoforms are known .

SYSTEMATIC NAME
IUBMB Comments
myo-inositol-phosphate phosphohydrolase
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. Two isoforms are known [4].
