Analysis Note

Protein determined by biuret.

Activity using maltose as substrate at pH 6.0 at 25 deg C is ~2X greater than that obtained using p-nitrophenyl-α-D-glucoside as substrate at pH 6.8 at 37 °C.

Application

α-glucosidase is potential enzyme for the biosynthesis of complex carbohydrates.

Biochem/physiol Actions

α-glucosidase hydrolyzes carbohydrates by acting on 1,4-α linkages. Inhibition of α-glucosidase is a prominent target in the management of non-insulin-dependent diabetes mellitus.
