General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency and waste prevention when used in starch hydrolysis research. For more information see the article in biofiles.

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.

Unit Definition

One unit will liberate 1.0 μmole of D-glucose from p-nitrophenyl α-D-glucoside per min at pH 6.8 at 37 °C.

Physical form

Lyophilized powder containing potassium phosphate buffer salt

Analysis Note

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.
Protein determined by biuret.

Two different α-glucosidase-producing thermophilic E134 strains were isolated from a hot spring in Kozakli, Turkey. Based on the phenotypic, phylogenetic and chemotaxonomic evidence, the strain was proposed to be a species of G. toebii. Its thermostable exo-α-1,4-glucosidases also were characterized

This study was to determine the sources, location and identity of α-glucosidases in dormant/germinating/outgrowing spores and growing cells of Geobacillus stearothermophilus ATCC 7953, an enzymatic activity in spores used in rapid tests of steam sterilization. α-Glucosidase activity in spores and

Fasting blood glucose level is usually used to diagnose diabetes, but is not a good predictor of postprandial hyperglycaemia, which is a more accurate measure of the metabolic defect underlying type 2 diabetes. Postprandial blood glucose levels may be elevated

Maltase-glucoamylase, a microvillous membrane ectoenzyme, was solubilized from rat intestinal mucosa by digestion with papain and subsequently purified to homogeneity with an overall yield of 10--20%. An antibody to the purified enzyme formed a single precipitin line in immunodiffusion experiments
