obsolete regulation of inositol-polyphosphate 5-phosphatase activity (obsolete GO:0010924)
OBSOLETE. Any process that modulates the rate or frequency of inositol-polyphosphate 5-phosphatase activity, the catalysis of the reactions: D-myo-inositol 1,4,5-trisphosphate + H2O = myo-inositol 1,4-bisphosphate + phosphate, and 1D-myo-inositol 1,3,4,5-tetrakisphosphate + H2O = 1D-myo-inositol 1,3,4-trisphosphate + phosphate.
