inositol-1,4-bisphosphate 1-phosphatase  M-CSA #856

Inositol polyphosphate 1 -phosphatase (l-ptase) removes the l-position phosphate from inositol 1,4-bisphosphate, yielding inositol 4-phosphate. l-Ptase is a ubiquitous monomeric enzyme that requires Mg2+ for activity and is potently inhibited by Li+, leading to its use in therapeutic targets of lithium treatment for manic-depressive illnesses.
