摘要

Abstract Methylumbelliferyl-β–cellobioside (MUF–G2) is a convenient fluorogenic substrate for certain β–glycoside hydrolases (GH). However, hydrolysis of the aglycone is poor with GH family 6 enzymes (GH6), despite strong binding. Prediction of the orientation of the aglycone of MUF–G2 in the+ 1 subsite of Hypocrea jecorina Cel6A by automated docking suggested umbelliferyl modifications at C4 and C6 for improved recognition. Four ...
