Abstract: The present disclosure relates generally to polysaccharide synthases. The present disclosure reveals that a subset of the CesA gene family encode XynS xylan synthases. As a result of the identification of XynS nucleic acids, and corresponding amino acid sequences that encode XynS xylan synthases, the present invention provides, inter alia, methods and compositions for modulating the level and/or activity of xylan synthase in a cell and/or modulating the level of xylan produced by a cell.

Abstract: The present invention is predicated on the discovery that a polysaccharide transferase purified from barley seedlings can catalyze the formation of covalent bonds between different polysaccharides, including between xyloglucans and cellulose, and between xyloglucans and (1,3;1,4)-?-D-glucans. The present invention thus provides, among other things, an isolated or substantially purified polysaccharide transferase, wherein said polysaccharide transferase is capable of catalyzing the formation of a covalent bond between a donor polysaccharide and an acceptor polysaccharide; or a functionally active fragment or variant of said polysaccharide transferase.

Abstract: A modified cereal (1→3,1→4)-&bgr;-glucanase is produced by the method of single point substitution in a native cereal (1→3,1→4)-&bgr;-glucanase enzyme, whereby the substitution:

Abstract: This invention relates to a (1→3, 1→4)-&bgr;-glucanase (glucanase EII endohydrolase) enzyme, whose amino acid sequence has been modified in order to provide an enzyme whose three-dimensional structure confers improved thermostability and/or pH stability. Specific modifications are based upon a comparison between the three-dimensional structure (1→3, 1→4)-&bgr;-glucanase and that of (1→3)-&bgr;-glucanase. The (1→3, 1→4)-&bgr;-glucanase gene has been modified by site-directed mutagenesis, and modified enzymes have been expressed in E. coli. Modified sequences, DNA molecules encoding them, plasmids, expression vectors and transgenic plants are disclosed.
