一般描述

α-淀粉酶是内切淀粉酶家族的成员。其分子量为57.6 kDa。α-淀粉酶由三个功能结构域组成，即A、B和C。A结构域是桶形（β/α）8结构，同时也是最大的结构域。B结构域通过二硫键与A结构域连接，并位于A结构域和C结构域之间。C结构域由β-折叠组成，并通过多肽链与A结构域连接。
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。当用于淀粉乙醇研究时，该产品经优化可提高能效和防止浪费。想了解更多信息，请参阅生物文件中的文章。

应用

α-淀粉酶可用于水解 α-连接的多糖（例如淀粉和糖原）α连接键。产品A3403来自地衣芽孢杆菌 ，并且是XII-A型。来自Sigma的α-淀粉酶已被用于各种植物研究，例如拟南芥的代谢研究 。

生化/生理作用

α-淀粉酶可水解三个或更多个D-葡萄糖单元通过α-(1,4)连接的多糖中的α-(1,4)葡聚糖键。 天然底物（如淀粉和糖原）可被分解成葡萄糖和麦芽糖。

注意

据报道，其在高达~90°C的温度下仍保持热稳定。

单位定义

在pH 6.9、温度20 °C条件下，一个单位可在3分钟内从淀粉中释放出1.0 mg麦芽糖。

外形

含有氯化钠和蔗糖的水溶液
