| Hazard Information | Back Directory | [Usage]
β-Amylase is a gel filtration molecular weight marker that can be used in gel filtration chromatography and protein chromatography. β-Amylase can be purified by affinity precipitation with alginate. | [Usage]
β-Amylase is used to hydrolyze α bonds of α-linked polysaccharides, such as starch and glycogen. β-Amylase, has been used in various plant studies, such as carbon starvation studies in Populus tremuloides 1 . β-Amylase, from barley, has been used to study how pressure and temperature affect catalytic activity. | [Chemical Properties]
Pale yellow or white lyophilized powder, soluble in water and dilute buffer solutions, insoluble in ethanol, pI 4.77, optimum pH 4.0-5.0. Stability: Optimal temperature 50-55°C; inactivation above 85°C; slightly acid-resistant, inactivation below pH 1.7; turns blue in the presence of iodine. Inhibitors include heavy metal ions (Cu2+, Ag+, H2+), urea, cyclohexyl amylose, methyl α-glucoside, and sulfhydryl reagents (4-chloromercuric benzoic acid, iodoacetammonium). The absorbance coefficient of a 1% aqueous solution at 280 nm is 12.3. Enzyme reaction: Starch (soluble) + nH2O═n maltose + dextrin. | [Uses]

| [Uses]
In starch processing, brewing, distilling, baking, animal feed, sewage treatment. | [Uses]
β-Amylase is a gel filtration molecular weight marker that can be used in gel filtration chromatography and protein chromatography. β-Amylase can be purified by affinity precipitation with alginate. | [General Description]
β-Amylases belongs to the class of amylolytic enzymes. | [Flammability and Explosibility]
Notclassified | [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. |
