This enzyme belongs to the family of lyases, specifically the class of phosphorus-oxygen lyases. The systematic name of this enzyme class is 1-phosphatidyl-1D-myo-inositol 1,2-diacyl-sn-glycerol-lyase (1D-myo-inositol-1,2-cyclic-phosphate-forming). Other names in common use include monophosphatidylinositol phosphodiesterase, phosphatidylinositol phospholipase C, 1-phosphatidylinositol phosphodiesterase, 1-phosphatidyl-D-myo-inositol inositolphosphohydrolase, (cyclic-phosphate-forming), 1-phosphatidyl-1D-myo-inositol diacylglycerol-lyase, and (1,2-cyclic-phosphate-forming). This enzyme participates in inositol phosphate metabolism.
