Thông tin tài liệu:

Important hydrogenbonding interactions between substrateOH-groups inyeasta-glucosidases andoligo-1,6-glucosidasefrom glycoside hydrolase family 13 have been identi®ed bymeasuring the rates of hydrolysis of methyla-isomaltosideand its seven monodeoxygenated analogs. The transition-state stabilization energy, DDGà, contributed by the indi-vidual OH-groups was calculated from the activities forthe parent and the deoxy analogs, respectively, accordingtoDDGà ˆ±RTln[(Vmax/Km)analog/(Vmax/Km)parent]....
