Abstract
The present invention discloses a method of synthesizing a novel form of cellulose I as well as methods of synthesizing a novel form of cellulose I in vitro. One method comprises contacting an activated saccharide substrate with an endoglucanase in an appropriate organic solvent/buffer ratio. The invention also encompasses a partially purified endoglucanase and a method of synthesizing cellooligosaccharides. A second method comprises contacting a nucleotide sugar with a purified glycosyl transferase in an appropriate buffer medium to insure polymerization and crystallization of parallel glucan chains from the enzyme/micelle complex to form cellulose I.
