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. | Defined by 7 residues: ASP:A-54GLU:A-79ASP:A-153ILE:A-155ASP:A-156THR:A-158ASP:A-317 | EC: 3.1.3.57 (PDB Primary Data) |
