Wall polysaccharides (including cellulose and a range of non-cellulosic polysaccharides such as xyloglucan and (1,3; 1, 4) - D-glucan is the basis of cell wall properties. In most cases, these interactions are considered non-covalent. A highly purified barley xylosyltransferase HvXET5 (EC 2.4.1.207), a member of the GH16 glycoside hydrolase, catalyzes in vitro between xylodexan and cellulose substrates and between xylodexan and (1,3; 1, 4) - A covalent bond is formed between D-glucans. xet may link different polysaccharides in the body, thereby affecting the strength, flexibility, and porosity of the cell wall.
