摘要:
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)-β-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.
