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...
(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...
Attached to the core structure may be a variety of side chain modifications which can be protein or tissue type specific and to date all GPI anchored proteins exhibit an additional ethanolamine phosphate on the 2-position of the mannose linked next to glucosamine (Kinoshita T. 1997 J. Biochem....
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 ...
The core structure of GPIs is conserved in most eukaryotic organisms and is comprised of EtNP-6Man伪1-2Man伪1-6Man伪1-4GlcN伪1-6 myo -Inositol-phospholipid (EtNP, ethanolamine phosphate; Man, mannose; GlcN, glucosamine) (Fig. 106.1a). The EtNP of the GPI core is amide-bonded to ...
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)....
