Abstract
Enzymatic hydrolysis of barley (1-->3),(1-->4)-beta-D-glucan using a r ecombinant (1-->3),(1-->4)-beta-glucanase from Bacillus licheniformis gives Glc beta 4Glc beta 3Glc isolated after acetylation in 49% yield. Conventional treatment produced the corresponding beta-fluoride which was carefully de-O-acetylated. A transglycosylation reaction with thi s substrate, catalyzed by the title enzyme, gave Glc beta 4Glc beta 3G lc beta 4Glc beta 4Glc beta 3Glc in 20% yield. (C) 1998 Elsevier Scien ce Ltd.
