Synthesis of non-hydrolysable mimics of glycosylphosphatidylinositol (GPI) anchors.
Synthesis of first generation non-hydrolysable C-phosphonate GPI analogs, viz., 6-O-(2-amino-2-deoxy-α-d-glucopyranosyl)-d-myo-inositol-1-O-(sn-3,4-bis(palmitoyloxy)butyl-1-phosphonate) and 6-O-(2-amino-2-deoxy-α-d-glucopyranosyl)-d-myo-inositol-1-O-(sn-2,3-bis(palmitoyloxy)propyl-1-phosphonate) 23b, is reported. The target compounds were synthesized by the coupling of α-pseudodisaccharide 21 w...
متن کاملYeast cells lacking all known ceramide synthases continue to make complex sphingolipids and to incorporate ceramides into glycosylphosphatidylinositol (GPI) anchors.
In yeast, the inositolphosphorylceramides mostly contain C26:0 fatty acids. Inositolphosphorylceramides were considered to be important for viability because the inositolphosphorylceramide synthase AUR1 is essential. However, lcb1Δ cells, unable to make sphingoid bases and inositolphosphorylceramides, are viable if they harbor SLC1-1, a gain of function mutation in the 1-acyl-glycerol-3-phospha...
متن کاملGlycosylphosphatidylinositol Anchors from Galactomannan and GPI-Anchored Protein Are Synthesized by Distinct Pathways in Aspergillus fumigatus
Glycosylphosphatidylinositols (GPIs) are lipid anchors allowing the exposure of proteins at the outer layer of the plasma membrane. In fungi, a number of GPI-anchored proteins (GPI-APs) are involved in the remodeling of the cell wall polymers. GPIs follow a specific biosynthetic pathway in the endoplasmic reticulum. After the transfer of the protein onto the GPI-anchor, a lipid remodeling occur...
متن کاملBiosynthesis of glycosylphosphatidylinositol membrane anchors.
Covalent modification of proteins with phosphatidylinositol (PI) was first suggested as a novel mechanism of membrane attachment when it was found that PI-specific phospholipase C (PI-PLC) could release alkaline phosphatase from tissue slices [1-5]. Subsequent compositional analysis of Trypanosoma brucei variant surface glycoprotein (VSG) [6,7], Torpedo acetylcholinesterase [8], erythrocyte ace...
متن کاملGlycosylphosphatidylinositol Anchors of Plasmodium falciparum
Induction of proinflammatory cytokine responses by glycosylphosphatidylinositols (GPIs) of intraerythrocytic Plasmodium falciparum is believed to contribute to malaria pathogenesis. In this study, we purified the GPIs of P. falciparum to homogeneity and determined their structures by biochemical degradations and mass spectrometry. The parasite GPIs differ from those of the host in that they con...
