"In the second step of GPI synthesis, N-acetylglucosaminyl-PI is hydrolyzed to yield glucosaminyl-PI and acetate. The phosphatidylinositol (PI) derivatives involved in this reaction are located in the endoplasmic reticulum membrane, as is the PIG-L enzyme that catalyzes it (Sharma et al. 1999; Pottekat and Menon 2004)."^^ . . . . . . .
