Description:
An Arabidopsis thaliana mutant (mur1) has less than 2 percent of the normal amounts of L-fucose in the primary cell walls of aerial portions of the plant. The survival of mur1 plants challenged the hypothesis that fucose is a required component of biologically active oligosaccharides derived from cell wall xyloglucan. However, the replacement of L-fucose (that is, 6-deoxy-L-galactose) by L-galactose does not detectably alter the biological activity of the oligosaccharides derived from xyloglucan. Thus, essential structural and conformational features of xyloglucan and xyloglucan-derived oligosaccharides are retained when L-galactose replaces L-fucose.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zablackis, E -- York, W S -- Pauly, M -- Hantus, S -- Reiter, W D -- Chapple, C C -- Albersheim, P -- Darvill, A -- New York, N.Y. -- Science. 1996 Jun 21;272(5269):1808-10.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Complex Carbohydrate Research Center, University of Georgia, Athens 30602-4712, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8650583" target="_blank"〉PubMed〈/a〉
