β-淀粉酶用于水解 α-连接的多糖（例如淀粉和糖原）的 α 键。β-淀粉酶已经用于各种植物研究，例如山杨的碳饥饿研究。来自大麦的 β-淀粉酶已用于研究压力和温度是如何影响催化活性的。应用： 我们致力于为您带来更加绿色的替代产品，这些产品遵守一项或多项绿色化学12项原则。该产品经过改进，可在用于淀粉乙醇研究时提高能效和防止浪费。有关详细信息，请参阅 《Biofiles》的文章。 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 ethanol research. For more information see the article in biofiles . Application: 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 . β -Amylase, from barley, has been used to study how pressure and temperature affect catalytic activity .

β-淀粉酶水解三个或更多个 α-（1,4）连接的 D-葡萄糖单元的多糖中的 α-（1,4）葡聚糖键。淀粉和糖原等天然底物被分解成葡萄糖和麦芽糖。纯的结晶 β-淀粉酶制剂由具有不同等电点的四种同工酶组成。在不存在还原剂的情况下，酶通过巯基非常快速地聚合。对氯甲基苯甲酸酯抑制该聚合和该酶活性。还原剂巯基乙醇或二硫苏糖醇可以完全恢复该活性。
