Reaction catalysed
  • 1D-myo-inositol 1,4,5-trisphosphate + H2O <=> 1D-myo-inositol 1,4-bisphosphate + phosphate
  • 1D-myo-inositol 1,3,4,5-tetrakisphosphate + H2O <=> 1D-myo-inositol 1,3,4-trisphosphate + phosphate
Comment(s)
This enzyme is distinguished from the family of enzymes classified under EC 3.1.3.36 by its inability to dephosphorylate inositol lipids.
