Genetic manipulations to increase phosphatidylethanolamine levels in gpi7螖 cells by overexpression of PSD1 restore cell growth at 37 掳C without restoring the addition of a substituent to Man2. The three putative ethanolamine-phosphate transferases Gpi13p, Gpi7p, and Mcd4p cannot replace each ...
As in other organisms, phosphoethanolamine (EtN‐P) transferases form part of the GPI anchor biosynthetic complex where they function to add ethanolamine phosphate side chains to the mannose residues in the GPI anchor glycan. To date, three EtN‐P transferases have been described in S. cerevisiae...

Glycosylphosphatidylinositol (GPI) anchors of mammals as well as yeast contain ethanolaminephosphate side chains on the α1–4- and the α1–6-linked mannoses of the anchor core structure (protein-CO-NH-(CH2)2-PO4-6Manα1–2Manα1–6Manα1–4GlcNH2-inositol-PO4-lipid). In yeast, ...
The structure of GPI-anchor bearing four mannoses is EtNP6(Man4α1-2)Man3α1-2(EtNP6)Man2α1-6(EtNP2)Man1α1-4GlcNα1-6(2-acyl) myo -inositol phospholipid (EtNP, ethanolaminephosphate; GlcN, glucosamine). All four mannoses are donated by dolichol-phosphate-mannose (Dol-P-Man)....
(where EtNP, Man, and GlcN are ethanolamine phosphate, mannose, and glucosamine, respectively). The 2-position of the first Man linked to GlcN is modified by EtNP in mammalian cells (Fig.1a). The biosynthesis of GPI occurs in the endoplasmic reticulum (ER) followed by attachment of the...
Moreover, they demonstrate that inositol acylation is required for mannosylation in the HeLa cell GPI biosynthetic pathway, whereas it is required for ethanolamine phosphate addition in the T.brucei GPI biosynthetic pathway. Related ReferencesSmith, T.K.; Paterson, M.J.; Crossman, A.; Brimacom...
After synthesis, GPI anchors are transferred to the proteins in the endoplasmic reticulum (ER) and are further remodeled by the elimination of acylphosphate and ethanolaminephosphate chains. GPI-APs are then transported from the ER to the plasma membrane through the Golgi apparatus. In the Golgi ...
