In enzymology, a glycosylphosphatidylinositol diacylglycerol-lyase (EC 4.6.1.14) is an enzyme that catalyzes the chemical reaction
- 6-(alpha-D-glucosaminyl)-1-phosphatidyl-1D-myo-inositol 6-(alpha-D-glucosaminyl)-1D-myo-inositol 1,2-cyclic phosphate + 1,2-diacyl-sn-glycerol
Hence, this enzyme has one substrate, 6-(alpha-D-glucosaminyl)-1-phosphatidyl-1D-myo-inositol, and two products, 6-(alpha-D-glucosaminyl)-1D-myo-inositol 1,2-cyclic phosphate and 1,2-diacyl-sn-glycerol.
This enzyme belongs to the family of lyases, specifically the class of phosphorus-oxygen lyases. The systematic name of this enzyme class is 6-(alpha-D-glucosaminyl)-1-phosphatidyl-1D-myo-inositol 1,2-diacyl-sn-glycerol-lyase [6-(alpha-D-glucosaminyl)-1D-myo-inositol 1,2-cyclic phosphate-forming]. Other names in common use include (glycosyl)phosphatidylinositol-specific phospholipase C, GPI-PLC, GPI-specific phospholipase C, VSG-lipase, glycosyl inositol phospholipid anchor-hydrolyzing enzyme, glycosylphosphatidylinositol-phospholipase C, glycosylphosphatidylinositol-specific phospholipase C, variant-surface-glycoprotein phospholipase C, 6-(alpha-D-glucosaminyl)-1-phosphatidyl-1D-myo-inositol, and diacylglycerol-lyase (1,2-cyclic-phosphate-forming).
