COMMENTARY
LITERATURE
synthesis
-
enzyme is a good tool for the synthesis of cellodextrins
synthesis
-
synthesis of cellulase inhibitors from reaction of 4-O-beta-D-glucopyranosyl-1-deoxynojirimycin or 6-O-beta-cellobiosyl-1-deoxynojirimycin as acceptors with glucose 1-phosphate as donors
synthesis
-
simple procedures for synthesizing various sugar length radioactive cellodextrins (G2G6) are developed using the Clostridium thermocellum cellobiose and cellodextrin phosphorylases from small building blocks of nonradioactive glucose-1-phosphate and radioactive glucose
