Synthesis of affinity get aimed for leaf-opening factor beta-glucosidase (LOFG) and affinity purification of LOFG are presented. Gluconamidine-based beta-glucosidase inhibitor was utilized for the ligand of the affinity gel. beta-Glucosidase exhibiting activity shift throughout the day was selectively purified from Lespedeza cuneata Don by the affinity gel. The resulting LOFG exhibited a high substrate specificity toward the leaf-opening factor. (c) 2007 Published by Elsevier Ltd.
