Usage

Description

BETA-AMYLASE is an enzyme that catalyzes the hydrolysis of α-1,4-glycosidic bonds in α-linked polysaccharides, such as starch and glycogen. It is found in various plants and has been used in numerous studies, including carbon starvation studies in Populus tremuloides and research on the effects of pressure and temperature on catalytic activity.
Used in Starch Processing Industry:
BETA-AMYLASE is used as a catalyst for the hydrolysis of starch, which is a key step in the production of various starch-based products.
Used in Brewing and Distilling Industry:
BETA-AMYLASE is used as a fermenting agent to break down starches into fermentable sugars, enhancing the efficiency of the brewing and distilling processes.
Used in Baking Industry:
BETA-AMYLASE is used as a dough improver to increase the softness and shelf life of baked goods by breaking down starches and improving the texture of the dough.
Used in Animal Feed Industry:
BETA-AMYLASE is used as a feed additive to improve the digestibility of starches in animal feed, promoting better nutrient absorption and overall animal health.
Used in Sewage Treatment Industry:
BETA-AMYLASE is used as a biological agent to break down starches and other organic matter in wastewater, aiding in the treatment and purification of sewage.
Used in Gel Filtration Chromatography:
BETA-AMYLASE is used as a gel filtration molecular weight marker, helping to determine the molecular weight of proteins and other molecules during gel filtration chromatography.
Used in Protein Chromatography:
BETA-AMYLASE can be purified by affinity precipitation with alginate, making it a useful tool in protein chromatography for the separation and purification of enzymes and other proteins.

Biochem/physiol Actions

β-Amylase hydrolyzes the α-(1,4) glucan linkages in polysaccharides of three or more α-(1,4) linked D-glucose units. Natural substrates such as starch and glycogen are broken down into glucose and maltose. Pure, crystalline β-amylase preparation consists of four isoenzymes with different isoelectric points. The enzyme polymerizes very rapidly through the sulfhydryl groups in the absence of reducing agents. p-Chloromercuribenzoate inhibits the polymerization and the enzymatic activity. The reducing agents mercaptoethanol or dithiothreitol can completely restore the activity.
