Food Grade EC 3.2.1.22

Alpha-galactosidase CAS No. 9025-35-8

Introduction

Α-galactosidase (α-galactosidase, EC 3.2.1.22), from Aspergillus niger, is a glycoside hydrolase, an exoglycosidase that catalyzes the water of α-galactosidate, which is decomposed by energy. Melibiose, also known as melibiase, can be used to improve and eliminate anti-nutritional ingredients in feed and soy foods. It can realize B→O blood group transformation, prepare universal blood type, and play an important role in enzyme replacement therapy of Fabry disease in the medical field. It can also act on complex polysaccharides containing α-galactosidic linkages, glycoproteins. And sheath sugar. Α-galactosidase also has a transgalactosylation effect in the case where the substrate concentration is highly enriched, and this feature can be used for the synthesis of a terpene polyester and the preparation of a cyclodextrin derivative. Alpha-galactosidase is a non-side-effect biological enzyme preparation for the development of functional foods, and has been certified as a safe substance by FDA, GRAS, WHO/FAP, and JACFA.

Characteristic characteristics

1. Temperature range: it is stable below 50 °C, the most suitable temperature is 60 ° C;

2. pH range: effective pH value is 4.0-8.0, optimal pH value is 5.0;

3. The effect of metal ions on enzyme activity: Cu2+, Zn2+, Mg2+ activating enzyme activities at a certain concentration: EDTA, Ba2+, Ag+ inhibited enzyme activity.

Applications

It can effectively catalyze α-galactosidic linkages and hydrolyze other anti-nutritional factors, reduce the incidence of digestive viscosity and diarrhea, and eliminate vegetative and animal bloating.

It can destroy the cell wall structure of plants, promote nutrient release, improve utilization efficiency, enhance immune function and disease resistance, and reduce the amount of antibiotics in feed.

It can improve the bleaching effect of paper by combining with xylanase, mannan plum and α-galactosidase.

It can also be used in the synthesis of sterol and in the preparation of cyclodextrin derivatives.

Packaging and storage
