General description

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

Application

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

Biochem/physiol Actions

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。

Physical form

含有氯化钠和蔗糖的水溶液

Other Notes

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。

Isomaltose-oligosaccharides (IMOs), as food ingredients with prebiotic functionality, can be prepared via enzymatic synthesis using α-glucosidase. In the present study, the α-glucosidase (GSJ) from Geobacillus sp. strain HTA-462 was cloned and expressed in Escherichia coli BL21 (DE3). Recombinant GSJ was

Biocatalytic transformations generally rely on purified enzymes or whole cells to perform complex transformations that are used on industrial scale for chemical, drug, and biofuel synthesis, pesticide decontamination, and water purification. However, both of these systems have inherent disadvantages related

Industrial enzymes are often immobilized via chemical cross-linking onto solid supports to enhance stability and facilitate repeated use in bioreactors. For starch-degrading enzymes, immobilization usually places constraints on enzymatic conversion due to the limited diffusion of the macromolecular substrate through
