In glycosylphosphatidylinositol (GPI)-anchor biosynthesis, the GPI-ethanolamine-phosphate transferase II complex catalyzes the conversion of ethanolamine-phosphate-mannose-mannose-(ethanolamine-phosphate)mannose-N-acetyl glucosamine-(acyl)phosphatidylinositol (EtNP-Man-Man-(EtNP)Man-GlcN-(acyl)PI) to EtNP-Man-(EtNP)Man-(EtNP)Man-GlcN-(acyl)PI.
