GPI anchors, which are glycosylphosphatidylinositol anchors, do not contain thioester bonds. They typically consist of a phosphoethanolamine linked to the C-terminus of a protein, a glycan core, and a phosphatidylinositol molecule, involving phosphodiester, glycosidic, and ester bonds, but not thioester bonds.
