ENZYME entry: EC 3.1.3.57

PURL: https://purl.expasy.org/enzyme/EC/3.1.3.57
Accepted Name
inositol-1,4-bisphosphate 1-phosphatase
Alternative Name(s)
inositol polyphosphate 1-phosphatase
Reaction catalysed
1D-myo-inositol 1,4-bisphosphate + H2O = 1D-myo-inositol 4-phosphate + phosphate
Comment(s)
  • Acts on inositol 1,4-bisphosphate and inositol 1,3,4-trisphosphate (forming inositol 3,4-bisphosphate) with similar Vmax for both substrates, but with a 5 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.
