l-Fucose-containing arabinogalactan-protein in radish leaves
The carbohydrate moieties of arabinogalactan-proteins (AGPs) have β-(1 → 3)-galactan backbones to which side chains of (1 → 6)-linked β-Gal residues are attached through O-6. Some of these side chains are further substituted with other sugars. We investigated the structure of L-Fuc-containing oligosaccharides released from the carbohydrate moieties of a radish leaf AGP by digestion with α-L-ara...
متن کاملDevelopmental Regulation of a Plasma Membrane Arabinogalactan Protein Epitope in Oilseed Rape Flowers.
We have identified and characterized the temporal and spatial regulation of a plasma membrane arabinogalactan protein epitope during development of the aerial parts of oilseed rape using the monoclonal antibody JIM8. The JIM8 epitope is expressed by the first cells of the embryo and by certain cells in the sexual organs of flowers. During embryogenesis, the JIM8 epitope ceases to be expressed b...

متن کاملStructure of the glycosylphosphatidylinositol anchor of an arabinogalactan protein from Pyrus communis suspension-cultured cells.
Arabinogalactan proteins (AGPs) are proteoglycans of higher plants, which are implicated in growth and development. We recently have shown that two AGPs, NaAGP1 (from Nicotiana alata styles) and PcAGP1 (from Pyrus communis cell suspension culture), are modified by the addition of a glycosylphosphatidylinositol (GPI) anchor. However, paradoxically, both AGPs were buffer soluble rather than membr...
متن کاملPolyproline II Confirmation in the Protein Component of Arabinogalactan-Protein from Lolium multiflorum.
Circular dichroism spectra of the arabinogalactan-protein from suspension-cultured Lolium multiflorum (ryegrass) endosperm cells demonstrate the presence of polyproline II conformation in the protein moiety of the proteoglycan. Subject to a number of theoretical and practical constraints of the method, it can be estimated that at least 30% of the protein component is in this conformation.
