ID   3.1.3.57
DE   inositol-1,4-bisphosphate 1-phosphatase.
AN   inositol polyphosphate 1-phosphatase.
CA   1D-myo-inositol 1,4-bisphosphate + H2O = 1D-myo-inositol 4-phosphate +
CA   phosphate.
CC   -!- Acts on inositol 1,4-bisphosphate and inositol 1,3,4-trisphosphate
CC       (forming inositol 3,4-bisphosphate) with similar Vmax for both
CC       substrates, but with a 5 times higher affinity for the bisphosphate.
CC   -!- Does not act on inositol 1-phosphate, inositol 1,4,5-trisphosphate or
CC       inositol 1,3,4,5-tetrakisphosphate.
