1D-myo-inositol-1,4-bisphosphate 1-phosphohydrolase
1D-myo-inositol 1,4-bisphosphate + H2O = 1D-myo-inositol 4-phosphate + phosphate [RN:R03393]
(other) R03427
1D-myo-inositol 1,4-bisphosphate [CPD:C01220];
H2O [CPD:C00001]
1D-myo-inositol 4-phosphate [CPD:C03546];
phosphate [CPD:C00009]
The enzyme acts on inositol 1,4-bisphosphate and inositol 1,3,4-trisphosphate (forming inositol 3,4-bisphosphate) with similar Vmax values for both substrates, but with a five-times higher affinity for the bisphosphate. Does not act on inositol 1-phosphate, inositol 1,4,5-trisphosphate or inositol 1,3,4,5-tetrakisphosphate.
