|Xylans are major noncellulosic polysaccharides of plant cell walls and are especially abundant in secondary cell walls. Xylans are chains of β-1,4-linked d-xylopyranosyl residues that can be substituted with arabinosyl, glucuronosyl (and its 4-O-methyl ether derivative), or acetyl residues (Ebringerová and Heinze 2000). Glucuronoxylans occur in angiosperm secondary cell walls, whereas Commelinoid monocotyledon primary cell walls have abundant glucuronoarabinoxylans (GAXs), and cereal grains have neutral arabinoxylans (Carpita 1996; Ebringerová and Heinze 2000). Structural features of xylans can vary during development (Obel et al. 2002; Suzuki et al. 2000). All xylans are thought to cross-link cellulose microfibrils and contribute to cell mechanical properties. Commercially, arabinoxylans are important for the functionality of flour and the nutritional value of animal feed.
|Generated using a neoglycoprotein (xylopentaose-BSA). It can recognise unsubstituted and relatively low-substituted xylans in several species. It can also accommodate more extensive substitution of a xylan backbone and binds strongly to wheat arabinoxylan.
