Structure of human glycosylphosphatidylinositol transamidase

Nature Structural & Molecular Biology, 2022
Glycosylphosphatidylinositol (GPI) molecules are complex glycophospholipids and serve as membrane anchors for tethering many proteins to the cell surface. Attaching GPI to the protein in the endoplasmic reticulum (ER) is catalyzed by the transmembrane GPI transamidase (GPIT) complex, which is essential for maturation of the GPI-anchored proteins.

Semisynthesis of a Glycosylphosphatidylinositol‐Anchored Prion Protein

Angewandte Chemie - International Edition, 2008
Pinning down the role of the anchor: The chemical synthesis of a cysteine-modified glycosylphosphatidylinositol (GPI) anchor provides access to homogeneous GPI-anchored prion protein through expressed protein ligation (see scheme). By this method, it should be possible to investigate the influence of the complex posttranslational GPI modification on ...

Chemical Biology of Glycosylphosphatidylinositol Anchors

Angewandte Chemie International Edition, 2012
AbstractGlycosylphosphatidylinositols (GPIs) are complex glycolipids that are covalently linked to the C‐terminus of proteins as a posttranslational modification. They anchor the attached protein to the cell membrane and are essential for normal functioning of eukaryotic cells. GPI‐anchored proteins are structurally and functionally diverse.

Production of a Nested Set of Glycosylphosphatidylinositol Structures from a Glycosylphosphatidylinositol-Anchored Protein

Analytical Biochemistry, 1995
Glycosylphosphatidylinositol (GPI) membrane anchors are synthesized in the endoplasmic reticulum of eukaryotic cells. Synthesis of the core GPI structure is achieved by the sequential transfer of monosaccharides and phosphoethanolamine to phosphatidylinositol. The assembly process can be reproduced in vitro using membrane preparations supplemented with

Structure, biosynthesis, and function of glycosylphosphatidylinositols

Biochemistry, 1990
The last few years have witnessed an explosion in our knowledge of GPI membrane anchors and related glycolipids and molecules where structure details are available, as illustrated in Figure 2. There is now sufficient information on a handful of these molecules to allow a detailed comparison of their chemical structures.
