摘要：

A high-performance liquid chromatographic method for the simultaneous determination of both the stereochemical outcome and the cleavage pattern of enzymatic action on unmodified sugar substrates is described. Three different enzymes were investigated by this method. Human pancreatic α-amylase hydrolyzed maltopentaose with retention of anomeric configuration, with the cleavage position being two glucose units from the reducing end. Cellulomonas fimi endoglucanase D hydrolyzed cellopentaose with retention of anomeric configuration and predominantly two glucose units from the reducing end. β-D-Xylosidase from Butyrivibrio fibrisolvens hydrolyzed o-nitrophenyl β-D-xylopyranoside with inversion of anomeric configuration. © 1994 Academic Press, Inc.
