Glycosylphosphatidylinositol phospholipase D (EC, GPI-PLD, glycoprotein phospholipase D, phosphatidylinositol phospholipase D, phosphatidylinositol-specific phospholipase D) is an enzyme with systematic name glycoprotein-phosphatidylinositol phosphatidohydrolase.[1][2][3][4] This enzyme catalyses the following chemical reaction

6-(alpha-D-glucosaminyl)-1-phosphatidyl-1D-myo-inositol + H2O 6-(alpha-D-glucosaminyl)-1D-myo-inositol + 3-sn-phosphatidate

This enzyme cleaves proteins from the lipid part of the glycosylphosphatidylinositol (GPI) anchors.
